摘要

    摘要
  • 摘要: 成功研制一种适合于TiNi形状记忆合金与不锈钢异质材料钎焊,并可安全应用于医学领域的新型AgCuZnSn银基钎料。对AgCuZnSn系钎料的熔化特性、微观组织、钎焊工艺特性及接头力学性能进行了研究。结果表明,所研制AgCuZnSn银基钎料成分为Ag51~53Cu21~23Zn17~19Sn7~9,固相线温度为590.0℃,液相线温度为635.3℃。该钎料主要由α-Ag固溶体、α-(Cu,Zn)固溶体和Ag-Cu共晶相组成,并含有少量Cu41Sn11、AgZn、Ag3Sn、Cu5Zn8等化合物。采用该钎料钎焊TiNi形状记忆合金与不锈钢,接头强度达320~360 MPa,同时TiNi形状记忆合金性能损失较小。新型钎料熔点低、钎焊冶金特性优异,钎焊接头界面冶金结合平直、致密。
    Abstract: A new-type AgCuZnSn filler metal suitable for brazing TiNi shape memory alloy and stainless steel and applying in biomedicine field has been developed. The melting characteristics, microstructure and brazing properties of AgCuZnSn filler metals were investigated and mechanical properties of the joints of TiNi shape memory alloy and stainless steel brazed with AgCuZnSn filler metals were evaluated. The results showed that the liquidus and solidus temperatures of the novel Ag51~53Cu21~23Zn17~19Sn7~9 filler metal were 590.0℃ and 635.3℃, respectively. The filler metal mainly consisted of α-Ag solid solution, α-Cu solid solution and Ag-Cu eutectic phase as well as a little Cu41Sn11, AgZn, Ag3Sn and Cu5Zn8 compounds. The tensile strength of the brazed joint of TiNi shape memory alloy and stainless steel using the filler metal reached to 320~360 MPa while the loss of shape memory effect and superelasticity of TiNi shape memory alloy was low. The developed AgCuZnSn filler metal had advantage of low melting point, brazing metallurgy characteristics and interface metallurgy unity and the brazed joint had good tenacity and plasticity.
