Microstructural Behaviors of Boron Modified LCB Titanium Alloy

Abstract:

Titanium has high specific strength, low elastic modulus, and good corrosion resistance. Especially, beta titanium alloys are used for jet engine, turbine blade in automobile and aerospace industries because of its good formability. Among the beta titanium alloys, LCB (Low-Cost Beta) titanium alloys were developed to make economical and mechanical advantages by not using high-cost beta stabilizer like Nb, Zr, Ta but using low-cost beta stabilizer like Mo, Fe, Cr, etc. In LCB titanium alloys, adding a small amount of boron makes grain refinement in cast ingot. This study has analyzed the changes of microstructure which can change mechanical properties after heat treatment and the plastic deformation in case of adding a small amount of boron.
