摘要
采用熔炼雾化法制备了不同组分的 AgCuTi钎料粉末,对粉末的氧含量、熔点、微观组织及硬度进行了测试与表征,并基于数理统计中的二次多项式回归方法和交互作用关系,利用JMP软件建立了各元素含量对 AgCuTi 合金钎料熔点影响的数学模型,通过回归拟合定量描述了各元素含量与熔点的变化关系.结果表明,Ti含量是影响 AgCuTi活性钎料粉末熔点及硬度的最显著因素,当Ti含量为 2%～4.6%时,钎料熔点随着Ti含量的增加而升高,熔点最低为 780℃左右,最高为 812℃左右,AgCuTi钎料硬度也随着Ti含量的增加而增大,从 122.79 HV增大到 248.82 HV,增大了 126.03 HV.本研究计算模型精度较高,可预测不同组分含量 AgCuTi合金钎料的熔点,研究结果可为 Ag-Cu-Ti体系合金钎料的选材应用提供参考.
Abstract
AgCuTi solder powder with distinct components was prepared utilizing the melting atomization method.The powder was subjected to tests and characterizations regarding oxygen content,melting point,microstructure,as well as hardness.On the basis of the quadratic polynomial regression method and interaction relationship in mathematical statistics,the mathematical model of the impact of each element's content on the melting point of AgCuTi solder was established by JMP software,and the relationship between each element's content and the melting point was quantitatively described by regression fitting.Furthermore,the research results revealed that Ti content significantly affected the melting point and hardness of the AgCuTi active solder powder.On the condition when the Ti content was 2%—4.6%,the melting point of the brazing material increased with the increase of Ti content,and the lowest melting point was about 780℃,and the highest was about 812℃.The hardness of the AgCuTi brazing material also increased with the increase of Ti content,and it increased by 126.03 HV from 122.79 HV to 248.82 HV.Moreover,the calculation model in this study has high accuracy and can predict the melting point of AgCuTi alloy brazing materials with various compositions.The research findings provide a reference for the selection and application of Ag-Cu-Ti alloy brazing materials.
