TL;DR: In this paper, the flow behavior of as-cast AZ91D magnesium alloy was evaluated by isothermal compression tests within the temperatures of 220 °C, 260′°c, 300′c, 340′C, and 380ò°C and the strain rates of 0.001, 0.1, 1 and 10s−1.

TL;DR: A powder metallurgy (P/M) Ti-22Al-25Nb (at%) alloy was prepared by spark plasma sintering of pre-alloyed powders at 1000˚C/80˚MPa/10˚min this article.

TL;DR: In this article, the results from the finite element analysis showed that effective strain was unevenly distributed in one-cycle strained sample and the non-uniformity would exist permanently with increasing deformation cycles.

TL;DR: In this paper, a modified constitutive model was established to describe the thixotropic behavior of the RUE strained alloys and the results revealed that three stages of elastic-like deformation, strain hardening deformation and rheological viscoplastic deformation were involved in thixoforming process.

TL;DR: In this article, the effects of deformation temperature and strain on microstructure characterization and nucleation mechanisms of dynamic recrystallization (DRX) were assessed by means of optical microscope (OM), electron backscatter diffraction (EBSD) and transmission electron microscope (TEM) techniques, respectively.
