Research on the influence of process parameters on the microstructure and mechanical properties of in-situ rolled Ti-6Al-4V fabricated by direct energy deposition

This study employs the in-situ-rolling DED composite additive manufacturing technique to fabricate Ti-6Al-4V alloy. Initially, the response surface methodology and analysis of variance are used to optimize the composite additive manufacturing process parameters. Based on this optimization, the alloy is formed, and a systematic investigation is conducted on the effects of in-situ rolling reduction and rolling speed on the microstructure and mechanical properties of the formed samples.
