- Effect of Severe Plastic Deformation and Subsequent Silicon Spheroidizing Treatment on the Microstructure and Mechanical Properties of an Al–Si–Mg Alloy
Nima Haghdadi, Abbas Zarei-Hanzaki, Megumi Kawasaki, Andre B. Phillion and Peter D. Hodgson

In order to make a compromise between strength and ductility, a subsequent heat treatment is carried out on a severely deformed A356 alloy. Heat treatment for 2 min at 540 °C changes the fracture mode from brittle to ductile, makes cracks to propagate intragranularly, and, in turn, enhances the ductility of the material from ≈8% to ≈15%.
- Polymer Derived Ceramics with β-Eucryptite Fillers: Filler-Matrix Interactions
Anna Fedorova, Ulf Betke and Michael Scheffler
Version of Record online: 24 MAR 2017 | DOI: 10.1002/adem.201700079
The phase composition and microstructure of Si–O–C/β-eucryptite composites exhibiting a zero-expansion behavior is evaluated using p-XRD and SEM-EDX. The β-eucryptite filler consumes silica from the Si–O–C matrix above 1 000 °C and finally transforms into a new β-spodumene phase.
- Evaluation of Textural Effect on the Rollability of AZ31 Alloys by Wedge-Shaped Sample Design
Renlong Xin, Maoyin Wang, Zhe Liu, Xingpin Chen, Guangjie Huang and Qing Liu
Version of Record online: 24 MAR 2017 | DOI: 10.1002/adem.201700035
Wedge-shaped AZ31 alloy plates with two kinds of initial textures are designed and rolled at five different temperatures. Then, the rollability under different conditions can be evaluated by observing the development of edge-cracks. It shows that the initial texture has little influence on the single-pass rollability at low temperatures, while the influence was significant for rolling above 150 °C.
- Influence of the Specimen Manufacturing Process on the Strength of Carbon-Bonded Alumina (Al2O3–C)
Henry Zielke, Anne Schmidt, Martin Abendroth, Meinhard Kuna and Christos G. Aneziris
Version of Record online: 23 MAR 2017 | DOI: 10.1002/adem.201700083
The present paper investigates the influence of the specimen manufacturing process on the strength of the material and the microstructure. The specimens are made of carbon-bonded alumina, which is used for open cell ceramic foam filters for metal melt filtration. The mechanical tests are performed by means of the ball on three balls test (B3B). The results are analyzed by means of Weibull distribution.
- Infiltration of Cellular Silicon by Molten Magnesium Alloys
Alexander Martin Matz, Bettina Stefanie Mocker, Johann Heimann and Norbert Jost
Version of Record online: 23 MAR 2017 | DOI: 10.1002/adem.201700023
In this study, intermetallic compounds on the example of Mg2Si1–xSnx are fabricated by investment casting of open-pore cellular Si structures and by, subsequently, infiltrating it with molten Mg alloys. The influence of processing parameters and of Sn content on the microstructural evolution is investigated and the initial state for a formation of the intermetallic compound is quantified by respect of the diffusion layer.
