The typical microstructure of the laser melting deposition (LMD) additive-manufactured Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy (TC11) contains heat-affected bands (HABs), narrow (NBs) and pools (MPs) that formed due to reheating superheating effects during layer-by-layer manufacturing process. Characterization results indicated coarse primary α lath (αp) transformed β (βt) structures were located in HABs, while fine basketweave structure was inside MPs. rapid modifications tensile properties...
Electropulsing treatment (EPT) in the liquid nitrogen (LN) circumstances, referred to as LN‐EPT, is utilized regulate microstructure and tensile properties of a cold‐rolled 316L austenitic stainless steel. The electropulsing effects between samples treated ambient environment at room temperature (RT) LN are compared. results confirm that LN‐EPT‐processed can also realize fully recrystallized microstructure, even Joule heat significantly suppressed compared with RT‐EPT samples. LN‐EPT show...
Microstructural evolutions of a cold-rolled CoCrFeMnNi high-entropy alloy (HEA) induced by electropulsing treatment at room temperature (RT-EPT) and liquid nitrogen (LN-EPT) were investigated compared. Finer recrystallized grains obtained LN-EPT compared to RT-EPT with the same discharge voltages. The recrystallization mechanisms discussed based on athermal thermal effects. former mainly contributes promoting nucleation nucleus, while latter affects new grain growth. Meanwhile, precipitation...
