用于钢丝绳、软管钢丝等方而的极细丝用线材,在冷加工中发生断丝的原因之一是有无延展性夹杂物的存在,因此,对夹杂物的特征和线材质量评价方法作了研究。本方法首先用扫描电子显微镜一电子探针显微分析器观察断线的断面,随后观察从断面中拣出的夹杂物形态、组成及大小。 One of the reasons for the occurrence of broken wires during cold working is the presence or absence of ductile inclusions in wires for ultrafine wires used for steel wires, hose wires, etc. Therefore, the characteristics of the inclusions and the method of evaluating the quality of the wire Study. The method first uses a scanning electron microscope-electron probe microanalyzer to observe the broken section, and then observe the shape, composition and size of inclusions picked from the section.
