Abstract

Calculation of Phase Diagram (CALPHAD) method was used to develop an additive manufacturing (AM) titanium alloy design strategy for new alloys in the Ti-Al-Fe system. This design strategy includes five key criteria addressing AM-processing suitability, mechanical properties and heat treatment capability. The methods for evaluating the design criteria were determined considering both physical implications and computational efficiency. Available experimental results agree well with CALPHAD predictions in the design map. CALPHAD method in this work can be applied for high-throughput early-stage assessments in large composition space for new AM titanium alloy development.
