| Abstract: | As commonly used tools, screw taps are prone to quenching cracks which can result in scrapping after quenching. This paper mainly focuses on the study of identifying the main reasons and propagation rules of the quenching cracks in T12 screw taps by studying the microscopic structures and original heat treatment process, and improving it. Experimental studies have shown that quenching cracks in T12 screw taps can be reduced and even eliminated effectively by optimizing the heat treatment process and choosing the parameters reasonablely. |
