Abstract

Titanium aluminide alloys are considered to be attractive materials for aerospace and automotive high-temperature applications due to their high specific strength, creep resistance, and heat resistance. However, their brittleness makes it difficult to manufacture complex-shaped components of these alloys using conventional processes making additive manufacturing a promising way to produce titanium aluminide parts. Additive manufacturing of titanium aluminide alloys involves high preheating temperatures affecting their microstructure; hence a proper heat treatment is needed to obtain desired properties. In this paper, a titanium aluminide alloy produced using Selective Laser Melting process with a high-temperature preheating was subjected to various heat treatments to study their effects on microstructure and properties of the alloy.
