In order to detect the carbide network in high carbon hypereutectoid steel wire rods accurately,two kinds of detection method of the carbide network are compared. 为了准确地检验高碳过共析钢盘条中的网状渗碳体,分别对选用硝酸酒精溶液侵蚀和碱性苦味酸钠水溶液热侵蚀两种显示方法进行了比较。
Hypereutectoid alloy. 过共析合金。
Taking black corundum particals as ceramics component, hypereutectoid steel as matrix metal, and Si-Fe as alloy, the crucibles of composites made of three layer components were obtained. 采用黑刚玉为陶瓷，过共析钢为基体金属，硅铁为合金构成三层复合材料坩埚。
Taking black corundum particals as ceramics component,hypereutectoid steel as matrix metal,and Si-Fe as alloy,the crucibles of composites made of three layer components were obtained. 采用黑刚玉为陶瓷,过共析钢为基体金属,硅铁为合金构成三层复合材料坩埚。目的分别是抵抗铝金属液体的浸蚀,使材料具有一定强度且能抵抗高温气体的氧化。
