一、问题的提出BM15高强度镁合金零件锻造废品率高,质量不稳定,经常出现裂纹、塑性差、流动性不好、填充不满型槽等,严重影响生产任务完成与产品工艺定型.影响质量的因素很多,其中有BM15原材料内部和表面质量;锻造加热温度;加热保温时间;模具工装温度与放料位置; First, the issue put forward BM15 high strength magnesium alloy parts forging scrap rate is high, the quality is unstable, often appear cracks, poor plasticity, poor liquidity, filling dissatisfied with the tank, etc., seriously affecting the production tasks and product technology stereotypes. There are many factors, including BM15 raw materials and surface quality of the interior; forging heating temperature; heating holding time; mold tooling temperature and release location;
