Yield strength (YS, 0.2% offset method), elongation at break (% EL) and ultimate tensile strength (UTS) were measured from the engineering stress-strain curves. Vickers microhardness (HV) (100 g f, 15 s hold) measurements were performed on the metallographic samples using a Future Tech...
LAM-processed Ti-6Al-4V forms a predominant martensitic-like microstructure. As a result of the high temperature gradient and fast cooling, the as-built material has very high strength (yield strength and ultimate tensile strength typically are >1.000 MPa); however, at the same time it is brit...
In terms of performance, the process parameters optimized by the indicators of yield strength in the three directions are A2B2C3D2. Considering the microstructure, by observing and measuring the microstructure of the deformed Ti-6Al-4V alloy, the suitable parameters of hot SCF is temperature of ...
