采用感应熔炼和电渣重熔制备合金锭,将不同热处理工艺制备的刀背材料切下3个鱼骨状试样,表面磨光后进行拉伸实验,结果取平均值。
The alloy ingot was prepared by induction melting and electroslag remelting. Three fishbone samples were cut from the knife back material prepared by different heat treatment processes, and the tensile test was carried out after the surface was polished. The results were averaged.
