摘要：

The effects of technological parameters on the interface morphology and shear strength of Fe3Al/18-8 diffusion bonded joints have been researched by means of a JXA-80 scanning electron microscope (SEM) and a digital tensile press test machine. Microstructural characteristics and fracture morphology near the Fe3Al/18-8 diffusion interface, obtained under conditions of various technological parameters, have been analysed using the SEM. The test results indicate that a diffusion bonded joint with higher shear strength (sigma(tau) = 226 MPa) may be obtained with a heating temperature T = 1020-1040degreesC, holding time t = 45-60 min and pressure P = 12-15 MPa.
