Martensite Phase Transform during Nitrogen-Spray Water Jet Quenching

Abstract:

Nitrogen-spray water jet quenching is a new kind of quenching, whose cooling velocity can be controlled. Thus different phase can be achieved according requirement, which can improve the characteristic of material. 9SiCr alloy steel was tested during Nitrogen-spray water jet quenching. The continuous cooling curves of 9SiCr under mixture of Nitrogen-spray water quenching for different pressure and mixture ratio of Nitrogen and spray water are obtained. After quenching, the metallographic structures were investigated, in which the uniform martensite was obtained after quenching.
