摘要
采用计算机程序控温、收集和处理数据系统反复测试了Na,sr,La对Al-Si共晶合金凝固过程的影响。结果表明,Na,Sr促使Al-Si共晶成核,使体系共晶析出温度升高。
The influence of Na, Sr, La on the solidification process of AI-Si eutectic alloys was repeatedly investigated by apparatus with a computer controlling temperature, collecting and treating data. It shows that Na and Sr in the melt promote the eutectic nucleation and raised the temperature of eutectic solidification, which is contrary to the traditional view point,
