一九八○年十月下旬第四技术交流站在一二八厂召开了弹性元件座谈会,站属18个单位主管弹性元件的领导和技术人员37人参加了会议。会议交流了弹性元件生产的经验;对存在的问题进行了分析,并探讨解决的办法和建议。代表就弹性元件存在的设计选材、材质、冷热工艺、检测等问题进行了讨论,根据量力而行的原则,提出了:研测硬度与弹性模量的相互关系;常用材料铍青铜、镍铍材料金相图谱;无损检测片状弹性材料分层、夹渣、气孔 The Fourth Technical Exchange Station in late October 1980 convened a symposium on elastic components at the 128th Factory. The leaders and technical staff of 18 units in charge of flexible components attended the meeting. The meeting exchanged experiences on the production of flexible components; analyzed the existing problems and explored solutions and suggestions. Representatives discussed the design selection, material, hot and cold process, and testing of the existence of elastic elements. Based on the principle of making ample efforts, the paper proposed the relationship between the measured hardness and the elastic modulus. The commonly used materials, such as beryllium bronze, nickel beryllium Material Metallography; Non-destructive testing Sheet elastic material layering, slag, porosity
