The Influence of Processing Parameters on Mechanical Properties and Microstructure of Welding Zone for Ti₃Al-TC4 Dual Alloy

Abstract:

It has been investigated that the influence of processing parameters on mechanical properties of weld zone for Ti-24Al-15Nb-1.5Mo and TC4 dual alloy welded by electron beam in vacuum. The results shows the remarkable influence factors are heat treatment regime and deformation for yield strength of welded dual alloy samples at room temperature tensile test, and the remarkable influence factor is forging temperature for the elongation in tensile test at 500°C. From the combined analysis about other properties at room temperature and 500°C, the microstructure of the weld seam, it can been gotten the optimum parameters of processing dual alloy, i.e. forging at 1020°C, soaking for 12 hour at 700°C, air cooling, about 40% deformation and using billet of rolling state.
