A TNM alloy with a chemical composition of Ti–44.45Al–3.80Nb–1.01Mo–0.29Si–0.14B is investigated to determine its microstructure evolution, dynamic recrystallization behavior, and the influence of the deformation conditions in isothermal compression tests. The feasible hot working window is obtained by analyzing the microstructures and the critical conditions for the initiation of dynamic recrystallization. The deformation mechanisms at different deformation stages are also discussed.

Crystallization behaviors of phase change materials (PCMs) are a prerequisite for storage/release of latent heat. In order to study interactions between PCM molecules and surface of the supports, the copper-based oxides, which display a controlled micromorphology and a large specific surface area, are reported in this work.

In the present paper, room temperature equal-channel angular pressing processing of a commercially pure titanium by a die with internal channel angle of 90° and taking advantage of core–sheath billet configuration is thoroughly investigated via experiment, finite element modeling, and analytical calculations. The following figure clearly shows how the core–sheath billet method can successfully severely deform titanium, as a hard-to-deform metal, regardless of core size.

- Microstructural Evolution and Properties of a Hot Extruded and HPT-Processed Resorbable Magnesium WE43 Alloy
Dexue X. Liu, Xin Pang, Denglu L. Li, Chenggong G. Guo, Jittraporn Wongsa-Ngam, Terence G. Langdon and Marc A. Meyers
Version of Record online: 6 DEC 2016 | DOI: 10.1002/adem.201600698
Microstructure evolution of HPT-processed resorbable WE43 alloy is investigated. A WE43 alloy with an initial grain size of ≈12 µm is processed by HPT to produce an ultrafine-grained microstructure and the sub-grain size is ≈200–300 nm after 10 turns. The microhardness shows significant improvement with increasing dislocation density. The tensile strength firstly increases and then decreases, while the elongation decreases after HPT deformation.
