Titanium and its alloys are highly desirable materials to be used in the aerospace industry due to its high strength and light weight. It is commonly used as airframe components on the airplane and could be subjected to different impact velocity. In this project, development of the microstructure of two types of titanium –CP-Ti and Ti-6Al-4V compressed at quasi-static and dynamic rates were investigated. The experiment was conducted using the INSTRON tester for quasi-static compression and SHPB for the dynamic compression testing. The microstructures of both materials at different strains were analysed and the microstructure of the Ti-6Al-4V specimens showed different deformation characteristic when subjected to quasi-static and dynamic compression.
