The compatibility of the austenitic AISI 304 steel with Pb-Bi-Sn alloy was analyzed.The AISI 304 steels were immersed in stagnant molten Pb-33.3Bi-33.3Sn alloy at 400,500 and 600 ℃ for different exposure times (100-2000 h)respectively.X-Ray diffraction spectrum (XRD)with a Y-4Q system (CuKa,λ=0.15478 nm)was used to identify the phases on the surface of specimens after exposing to Pb-Bi-Sn liquid metal (LM).The surface and cross section of the specimens were analyzed by means of scanning electron microscopy (SEM)and energy dispersive X-ray ana...
