    1. Study of Reinforcing Mechanisms in TRIP-Matrix Composites under Compressive Loading by Means of Micromechanical Simulations (pages 542–549)

      Stefan Prüger, Lars Mehlhorn, Uwe Mühlich and Meinhard Kuna

      Version of Record online: 20 MAR 2013 | DOI: 10.1002/adem.201200323

      Particle reinforced TRIP-matrix composites, consisting of partially stabilized zirconia particles embedded in a TRIP-steel matrix, show a very heterogeneous phase transformation behavior. It is due to both the stress concentration and the void formation as a result of interface decohesion. The figure depicts the distribution of martensite volume fraction in the matrix and the volume fraction of monoclinic zirconia in the particle after uniaxial compression ϵ = 0.35.

    2. Influence of Matrix Strength and Volume Fraction of Mg-PSZ on the Cyclic Deformation Behavior of Hot Pressed TRIP/TWIP-Matrix Composite Materials (pages 550–557)

      Alexander Glage, Christian Weigelt, Jan Räthel and Horst Biermann

      Version of Record online: 3 APR 2013 | DOI: 10.1002/adem.201200334

      The fatigue behavior of particle reinforced MMCs with high-alloyed CrMnNi steels as matrix reinforced with partially stabilized zirconia (Mg-PSZ) is investigated. It is shown, that the fatigue behavior is influenced significantly by the chemical composition of the steel matrix and Mg-PSZ volume fraction. Depending on the chemical composition, the high-alloyed steels show the TWIP and TRIP effect under cyclic loading.

    3. Effect of Manganese on Microstructure and Mechanical Properties of Cast High Alloyed CrMnNi-N Steels (pages 558–565)

      Marco Wendler, Andreas Weiß, Lutz Krüger, Javad Mola, Armin Franke, Alexander Kovalev and Steffen Wolf

      Version of Record online: 2 APR 2013 | DOI: 10.1002/adem.201200318

      The effect of the manganese content (0–11%) on the transformation temperatures, the mechanical properties, and microstructure development of five highly alloyed 14Cr–XMn–6Ni cast stainless steels with 0.1% nitrogen is studied. The temperature dependence of tensile properties in alloys is explained on the basis of varying contributions to the strength and ductility of deformation-induced martensite and twin formation mechanisms.

    4. Electron Beam Welding of High Alloy CrMnNi Cast Steels with TRIP/TWIP Effect (pages 566–570)

      Anja Buchwalder, Karsten Rüthrich, Rolf Zenker and Horst Biermann

      Version of Record online: 3 APR 2013 | DOI: 10.1002/adem.201200355

      Thumbnail image of graphical abstract

      Electron beam welding of high alloy CrMnNi cast steels showing the TRIP and/or TWIP effect proved to be advantageous because of its short time energy input, which results in minimized thermal loading of the base material. Crack and pore-free welding seams with depths up to 26 mm were produced. EBSD investigations showed that the deformation mechanisms in the welding seam are qualitatively the same as in the base material.

    5. Microstructure Defects Contributing to the Energy Absorption in CrMnNi TRIP Steels (pages 571–582)

      Daria Borisova, Volker Klemm, Stefan Martin, Steffen Wolf and David Rafaja

      Version of Record online: 5 APR 2013 | DOI: 10.1002/adem.201200327

      Thumbnail image of graphical abstract

      Microstructure defects and their interactions contributing to the high energy absorption in highly alloyed austenitic CrMnNi TRIP steels: dislocations, stacking faults, Lomer-Cottrell locks, stacking fault tetrahedra, dislocation clusters; the ϵ-martensite, twinned austenite and the α′-martensite, caused by the fluctuation of the stacking fault density and the lattice shearing within deformation bands, are analyzed using REM and TEM/ HRTEM.

    6. The Thermophysical Properties of Liquid TRIP/TWIP-Steel Alloys Using the Maximum Bubble Pressure Method (pages 583–589)

      Tobias Dubberstein and Hans-Peter Heller

      Version of Record online: 19 APR 2013 | DOI: 10.1002/adem.201200310

      The surface tension of copper, AISI 304 and the Cr-Mn-Ni steels are determined via the maximum bubble pressure method using zirconia capillary tubes. Oxygen adsorption in Cr-Ni steel decreases surface tension. Manganese is responsible for a decrease of surface tension values in Cr-Mn-Ni alloys. For Cr-Ni and Cr-Mn-Ni stainless steels temperature coefficient of surface tension changed to positive.

    7. Mg-PSZ Reinforced TRIP-Steel MMCs – In Situ CT Investigations of Cruciform Samples under Compressive Loading (pages 590–599)

      Uta Ballaschk, Harry Berek, David Ehinger, Christos G. Aneziris and Lutz Krüger

      Version of Record online: 10 APR 2013 | DOI: 10.1002/adem.201200348

      Thumbnail image of graphical abstract

      Mechanical in situ investigations on cruciform members of square-celled TRIP-steel/Mg-PSZ honeycomb structures are presented under uniform compressive load in a computer tomograph (XCT). The mechanical and structural characteristics of the cell wall node elements are compared to the damage mechanisms of the complete honeycomb specimens. Phase transformations in the Mg-PSZ particles are determined by EBSD.

    8. Microstructure Changes in TRIP Steel/Mg-PSZ Composites Induced by Low Compressive Deformation (pages 600–608)

      Stefan Martin, Sabine Decker, Lutz Krüger, Ulrich Martin and David Rafaja

      Version of Record online: 13 MAY 2013 | DOI: 10.1002/adem.201200330

      Strength and work hardening of TRIP matrix composite materials depend strongly on the testing temperature. Due to a temperature dependent driving force for the α′-martensite formation and a changing stacking fault energy in the metastable austenitic matrix, completely different deformation mechanisms can be observed at room temperature and at 100°C. With the transition from the formation of intrinsic stacking faults at 20°C to extrinsic stacking faults at elevated temperatures, the TRIP effect is substituted by mechanical twinning. The stress induced martensitic transformation in the reinforcing zirconia particles increases the stress level of the MMC further.

    9. Thermodynamic-Mechanical Modeling of Strain-Induced α′-Martensite Formation in Austenitic Cr–Mn–Ni As-Cast Steel (pages 609–617)

      Alexander Kovalev, Marco Wendler, Andreas Jahn, Andreas Weiß and Horst Biermann

      Version of Record online: 14 MAY 2013 | DOI: 10.1002/adem.201200340

      Thumbnail image of graphical abstract

      The microstructure evolution during deformation and the mechanical behavior of an austenitic Cr–Mn–Ni as cast steel are investigated at various temperatures. The deformation-induced twinning and ϵ/α′-martensite formation – the TWIP and TRIP effects – occur in the investigate steel depending on the deformation temperature. For characterization and illustration of the TRIP/TWIP effects the STT and DTT diagrams are developed. Finally, the α′-martensite nucleation threshold is determined, and an equation is proposed to describe the volume fraction of strain-induced α′-martensite as a function of the total driving force.

    10. Experimental Investigation and Thermodynamic Modeling of the ZrO2–MgO System (pages 618–626)

      Dmytro Pavlyuchkov, Galina Savinykh and Olga Fabrichnaya

      Version of Record online: 17 MAY 2013 | DOI: 10.1002/adem.201200316

      Thumbnail image of graphical abstract

      The ZrO2–MgO phase diagram is experimentally studied using XRD, SEM-EDX, and DTA. The ZrO2-based solutions are modeled as ionic solutions using compound energy formalism. The thermodynamic parameters are optimized using own and literature experimental data. The calculated ZrO2–MgO phase diagram is used to interpret the microstructure and phase transformations observed in the industrial Mg-PSZ material in as-received and heat treated states.

    11. Interface Phenomena Responsible for Bonding between TRIP Steel and Partially Stabilised Zirconia as Revealed by TEM (pages 627–637)

      Anna Poklad, Mykhaylo Motylenko, Volker Klemm, Gerhard Schreiber, Stefan Martin, Sabine Decker, Barbara Abendroth, Markus Haverkamp and David Rafaja

      Version of Record online: 20 JUN 2013 | DOI: 10.1002/adem.201200344

      The phase composition and the orientation relationship of several crystallites at the PSZ/TRIP steel interface before and after a mechanical deformation are studied in thin films and in a bulk composite sample using HRTEM, EDX and EELS. The analysis of the zirconium N2,3 edge in the electron energy loss spectra allows to distinguish the cubic, tetragonal and monoclinic ZrO2 phases from each other.

    1. Temperature Effects on the Deformation Behavior of High-Density TRIP Steel and Particle-Reinforced TRIP Steel/Zirconia Honeycombs Under Quasi-Static Compressive Loading (pages 646–657)

      David Ehinger, Lutz Krüger, Ulrich Martin, Christian Weigelt and Christos G. Aneziris

      Version of Record online: 21 MAY 2013 | DOI: 10.1002/adem.201200345

      Thumbnail image of graphical abstract

      This study is focused on the effects of material strengthening and reinforcing mechanisms on the crush resistance, deformability, and energy absorption capability of square-celled TRIP steel and TRIP steel/zirconia composite honeycomb structures under quasi-static out-of-plane compressive loading over a wide range of test temperatures. The microstructure and phase evolution in the cell wall material is investigated by magnetic force balance and EBSD measurements considering different deformation stages.
