摘要
运用X射线衍射仪、扫描电镜、显微硬度计等仪器设备,研究了0.8 T近强磁场作用对Sn-9Zn钎料合金组织和性能影响。研究结果表明:近强磁场可促进Sn-9Zn钎料合金显微组织显著细化,使熔化温度下降2℃,显微硬度提高11%。分析认为,由于外加磁场可促进Sn-9Zn钎料合金在特定晶面迅速结晶形核以及作用于液态钎料合金的的洛仑兹力对钎料作负功,从而促进Sn-9Zn钎料合金组织和性能的改变。
Effects of high magnetic field of 0.8 T on microstructure and property of Sn-9Zn solder alloy was investigated by means of XRD,SEM and microhardness.The result show that high magnetic field can remarkably refine microstructure of Sn-9Zn solder alloy,decreasing melted temperature of 2 ℃ and increasing the microhardness of 11% at same time.Analysis shows that the high magnetic field can promote Sn-9Zn solder to crystalize at special plane and the Lorentz force do negative work to the liquid solder metal and thus cause the changes on microstructure and property of Sn-9Zn solder alloy.
