•A novel microstructure in SLM Ti-6Al-4V alloy was constructed by electropulsing.•The calculation results showed that the diffusion distance of V was minimal.•Electropulsing induced more al atoms in the βt region and caused higher strength.•Low degree of element segregation resulted in higher Rp and...
