引线框架用C19400合金板带制备工艺研究现状
Research status on the preparation process of C19400 alloy sheets for lead frame
摘要
Abstract
C19400 alloy has become the most widely used lead frame material due to its excellent mechanical properties,high electrical conductivity,and low-cost advantage,which is extensively applied in electronic information,electrical control,power transmission,and rail transit fields.Based on the chemical composition,microstructure,and strengthening mechanisms of C19400 alloy,this study systematically reviews the structure-property relationship between microstructural evolution and macroscopic properties under various processing technologies,including semi-continuous casting,homogenization heat treatment,hot rolling,solution treatment,cold rolling,aging,and stress relief annealing.Each of these processing steps exerts a significant impact on the alloy's microstructure and properties,thus requiring strict control of process parameters during production.The current research status of C19400 alloy is summarized,aiming to provide theoretical guidance for the design of new alloys and process optimization,thereby promoting the research and development of high-performance new alloys and significantly improving the comprehensive properties of traditional alloy materials.关键词
