| 摘 要： | Based on a large amount of dissection at welded interface and quantitative microscopic examination of welded rate, the suitable limit grey scale value was determined, and the welded rate of superplastic solid-state welding interface of heterogeneous steel was systematically studied by means of self-made ultrasonic C-scanning imaging inspection system. The experimental results show: the welded state of superplastic solid-state welding interface of heterogeneous steel can be conducted to be more accurately, reliably and quickly inspected by means of this system, and the ultrasonic testing results are good consistent with actual examination results of the interface defective distribution. Within the extent of the suitble welded rate ,thewelded rate in 40Cr/T10A superplastic welding process tested by this system is linear with its tensile strength of joint.
