Microstructure evolution and dynamic recrystallization of spray-formed Al–Zn–Mg–Cu alloy under hot deformation

Hot Deformation Behavior and Microstructural Evolution of a High-Strength Mg-Gd-Y-Zr Alloy

Mg-Gd-Y-Zr alloys, with strong age-hardening and thermal stability, are ideal for lightweight load-bearing components, yet forming large complex parts is limited by high sensitivity to hot deformation parameters. This work investigates the hot deformation behavior and microstructure evolution of a Mg-9Gd-4Y-0.5Zr (wt.%...

Investigation on deformation mechanism and recrystallization behavior of a Mg–Gd–Y–Zn–Mn alloy by hot compression

Hot Deformation Behavior and Microstructure Evolution of a Novel Near-α Titanium Alloy with Initial Lamellar Microstructure During Hot Compression

The hot deformation behavior and microstructure evolution of a novel near-α Ti65 titanium alloy with an initial lamellar microstructure were investigated by isothermal compression. Compression tests were conducted at 950–1010 °C in the α + β phase region and 1050–1110 °C in the β phase region, with strain rates of 0.01...

Effect of Temperature and Strain Rate on the Thermomechanical Response and Dynamic Restoration Mechanisms of Ti-6Al-4V Alloy During Forging

The thermomechanical behavior of the Ti-6Al-4V (Ti64) alloy under hot deformation is determined by a complex interplay between strain hardening and thermally assisted restoration processes that finally lead to the formation of the resultant microstructure and mechanical properties. In this research, the effects of defo...

Effect of Plastic Deformation on the Microstructure and Mechanical Properties of an Al-Li-Cu-Mg Alloy after Aging

Recrystallization and texture evolution in friction stir welded 7050-T7451 aluminum alloy

Friction stir welding was performed on 7050-T7451 alloy of the Al-Zn-Mg-Cu system. Sound welds without defects were produced using a rotation rate of 600 rpm and a traverse speed of 100 mm/min. The as-received base material (BM) displayed overaged microstructures with coarse, elongated grains and fine, partially recrys...
