Sr对ZL104合金的变质作用
Modification Effect of Sr on ZL104 Alloy
【摘要】 研究了AlSr中间合金对ZL104合金中共晶Si相的变质规律。结果表明,Sr对共晶Si有很好的变质效果,Si相由长针状变成尺寸为1~2μm的圆点状颗粒,变质效果长达4h不衰退。变质后力学性能有较大提高
【Abstract】 The modification effect of Al Sr alloy on microstructure and mechanical property of ZL104 alloy was studied.It shown that Sr had the good effects on alloy and the modification effects could be kept more than 4 hours.The Si phase was modified to spherical shape of 1~2μm diameter,and the mechanical property of ZL104 alloy was improved significantly.
