Experimental research on hot-tearing crack sensitivity
Experimental research on hot-tearing crack sensitivity
摘要
Hot-tearing cracks usually form near the solidus temperature. It is caused by a combination of tensile stress and metallurgical embrittlement. In order to quantify embrittlement and to incorporate it in the thermal-stress analysis, many different criteria have been developed. Among them,the submerged split-chill tensile （SSCT） test is an efficient one. This paper tries to use SSCT to estimate the critical strain of hot tearing for some steels.
