Ti-6Al-4V alloy is a well-known lightweight material occupying more than 50% of the entire global titanium market. Particularly, due to its high specific strength, excellent heat resistance, and corrosion resistance, it holds significant industrial potential as a material for aircraft engines and space launch vehicles. However, despite its various advantages, its low elongation and machinability limit its use as a general industrial material. To address this issue, we intend to implement the TRIP mechanism to Ti-6Al-4V alloy systems. As the beta phase stability in Ti-6Al-4V alloy is rather low, a novel alloy composition design is required by adding beta-stabilizing elements. For this study, the Bo-Md diagram was chosen as a general alloy design guideline. Particularly, the beta phase composition was plotted on the diagram. Using this newly suggested guideline alongside with the conventionally known [Mo]eq, a novel Ti-6Al-4V alloy system exhibiting TRIP behavior was developed successfully. |
