Effect of interlayer temperature on microstructure evolution and mechanical performance of wire arc additive manufactured 300M steel

The 300M steel straight wall parts (SWPs) are fabricated by wire arc additive manufacturing based on cold metal transfer technology. The effects of interlayer temperature on microstructure evolution and mechanical performance in the different regions of the SWPs are investigated. The results show th...
