DIFFUSION JOINING OF METAL MATERIALS BY HIP

The paper has briefly described the concepts and technologies of diffusion joining by HIP, as well as the joining between steel/Ti, Mo/Ti, W/Mo, Mo/Mo, FGH 95/FGH95, stainless steel/stainless steel shears by using HIP. Experimental results have been radimentarily evaluated by microscopy, electron probe, SEM, EXDA,micro-hardness and etc.
