The effects of small additions of calcium (0.1% and 0.5%11 All compositions in weight percentage.) on the dynamic recrystallization behavior and mechanical properties of as-extruded Mg-1Mn-0.5Al alloys were investigated. Calcium microalloying led to

Strain-induced precipitation (SIP) behaviors of 7Mo super-austenitic stainless steel (SASS) were studied by strain relaxation test at 850 °C. Our results reveal that sigma (σ) phases are the predominant SIP of 7Mo SASS, with the chemical formula of

Dynamic α precipitation with hot deformation is commonly adopted to obtain equiaxed α for tailoring the mechanical properties of Ti alloys. The formation of an equiaxed shape rather than the typically observed α plate is closely correlated with th

In this work, the homogenized Al–Li alloys were compressed at different strains (20%–80%) under medium (370 °C) and high temperatures (470 °C), and their microstructures were characterized by SEM, EBSD, and TEM. The evolution of dynamic precipi
