半固态挤压成形ZCuSn10铜合金的微观组织研究
摘要
对采用冷轧-重熔应变诱导熔化激活法制备的ZCuSn10铜合金坯料进行了半固态挤压成形和组织演变分析
研究了ZCuSn10铜合金的半固态挤压成形性。结果表明
采用冷轧-重熔法制备的ZCuSn10铜合金坯料具有均匀、细小颗粒的半固态组织
在960℃保温25min后挤压成形可获得表面光洁、组织细小、分布均匀的挤压件。
Abstract
The semi-solid thixo-extrusion ZCuSn10 copper alloy prepared by strain induced melt activated(SIMA)method with cold rolling and remelting was carried out.The semi-solid extrusion formability of ZCuSn10 copper alloy was described through the analysis of microstructure evolution.The results indicate that microstructure of ZCuSn10 alloy billets by SIMA method with cold rolling and remelting exhibits uniform
fine particles.The extrusion part with surface finish
fine and homogeneous microstructure can be obtained at 960 ℃for 25 min.
