By developing a void-free additive manufacturing (AM) process for titanium alloy, the author demonstrates a significant improvement in fatigue resistance, surpassing traditional AM and forged alloys. The main thesis revolves around the potential of eliminating microvoids to enhance the fatigue properties of structural materials.

We successfully rebuild an approximate void-free additive manufacturing microstructure in Ti-6Al-4V titanium alloy by the development of a void-free additive manufacturing processing technique through an understanding of the asynchronism of phase transformation and grain growth.
