本文以GCr_(15)和W_(18)Cr_4V钢作材料,用磁学法(电流换向法)测定钢中残余奥氏体量,提出了一种碳化物修正的新公式,并为实现快速、恒等电流换向而采用了一种新方法。
In this paper, GCr_ (15) and W_ (18) Cr_4V steel were used as materials to measure the amount of retained austenite in steel by magnetic method (current steering method). A new formula for carbide modification was proposed. , A constant current commutation and adopted a new method.
