Experimental Study of Electron Beam Welded QCr0.8 Bronze Joint

Abstract:

The butt welding test has been performed on QCr0.8 bronze by electron beam welding. Microstructure of the joint was examined by optical microscopy and scanning electron microscopy with EDS. Microhardness of the joint was determined to evaluate the mechanical property of the joint. The fusion zone and the heat affected zone became the weak area of the joint due to the growth of grains and the redissolve of strengthening phase. The decrease of strengthening phase has a major influence on the microhardness reduction of the joint..
