Laser, tungsten inert gas, and metal active gas welding of DP780 steel: Comparison of hardness, tensile properties and fatigue resistance
TL;DR: In this paper, the microstructural properties, tensile properties and low-cycle fatigue properties of a dual-phase steel (DP780) were investigated following its joining by three methods: laser welding, tungsten inert gas (TIG) welding, and metal active gas (MAG) welding.
Journal ArticleDOI
Multiple twinning modes in rolled Mg–3Al–1Zn alloy and their selection mechanism
TL;DR: In this article, a combined examination of the in situ electron backscatter diffraction technique and Schmid factor (SF) analysis revealed that the selection mechanism of each type of twinning mode is governed by the combined effect of the SF and grain size.
Journal ArticleDOI
Tension–compression yield asymmetry in as-cast magnesium alloy
TL;DR: In this article, the tension-compression asymmetry in a randomly textured cast magnesium alloy was investigated in terms of its {10 − 12} twinning characteristics, which resulted in a lower yield strength and higher strain hardening under tension than compression.
Journal ArticleDOI
Dynamic recrystallization behavior and microstructural evolution of Mg alloy AZ31 through high-speed rolling
TL;DR: In this article, the authors investigated dynamic recrystallization (DRX) behavior and microstructural and textural variations of Mg alloy AZ31 during a high-speed rolling (HSR) process.
Journal ArticleDOI
Enhancing mechanical properties of a low-carbon microalloyed cast steel by controlled heat treatment
TL;DR: In this paper, detailed studies were made on the optimization of microstructure and mechanical properties of a low-carbon microalloyed cast steel through control of heat treatment conditions.
