英文摘要	Co-Al-W superalloy is a novel cobalt-based superalloy with the precipitation strengthening phase of ternary compound gamma-Co-3(Al,W). In order to study the cracking behavior of Co-8.8A1-9.8W-0.2B cladding layer on 304 stainless steel with TIG welding, the phase composition and relative contents at different positions of the cladding layer were investigated by thermodynamic simulation calculation of JMatPro software and experimental verification. The results show that the phase composition is the same at different positions of the cladding layer, but the content of those phases are not alike. Combining phase composition and contents of the cladding layer, the surface cracks of cladding layer are mainly hot cracks, which come from the integrated effect of the thermal stress, the phase transformation stress and the Laves phase.
