摘要
Isostatic diffusion bonds were produced between Ti-6Al-4V and Super Alpha-2 sheet materials at temperatures of 920-940 degrees C and pressures of 6-10 MPa. The diffusion bonds were evaluated using optical microscopy, lap shear testing and scanning electron microscopy of the lap shear fracture faces. The results of X-ray microanalysis carried out on the bond interface region showed that substantial diffusion of niobium and molybdenum had occurred from the Super Alpha-2 to the Ti-6Al-4V. This caused a local suppression of the beta transus in the Ti-4Al-4V alloy and on subsequent cooling the beta phase decomposed to give a microstructure of fine acicular alpha phase and retained beta phase in the bond region.
