In order to control the quality induced by the grain growth during high temperature annealing of Fe-Ni-Co-Cu type alloys, Zr modification can effectively control the grain size to ASTM grade 5 to 6 during annealing at 1050℃.The form of existence of Zr in the alloys is investigated to search for the mechanism of grain growth retarded by Zr.The effect of the structure and size of particles formed by Zr on retarding the grain boundary mobility is analyzed and the factors influencing the effect of Zr retarding grain growth are discussed.It is shown that the addition of Zr in these alloys has improved the properties concerned with grain refinement, such as the characteristics of the grain boundary penetration by brazing alloys, workability, chemical stability, anti-SCC ability etc., and had little effect on its thermal expansion, mechanical properties and weldability by of TIG welding. These alloys modified by proper amount of Zr showed good performance during application to instruments and apparatus.

An investigation was made of the influence of Zr addition on the hightemperature phase transformation, the martensitic forward-and-back transformationand the shape memory effect of a Cu-Zn-Al base alloy by means of the differen-tial scanning calorimetry (DSC), X-ray diffraction and TEM. An addition of 0.35wt-% Zr may effectively inhibit the precipitation of α and γ phases and facilitatethe order transformation β_2→DO_3→18RM. It was observed that the M_s—M_f and A_s—A_f temperature ranges of the alloy are rather narrow, its activation energy ofmartensitic transformation is minimum and its interface between two martensitevariants is more mobile, thus, its shape memory effect is the optimum.

采用示差扫描热分析(DSC)、X射线衍射及透射电镜,研究了Zr对Cu-Zn-Al合金高温相变、马氏体正逆转变以及形状记忆效应的影响。结果表明,添加Zr0.35wt-%时,能有效地抑制α,γ相析出,促进β_2→DO_3→18RM转变。(M_s-M_f)及(A_s-A_f)温度区间较窄,马氏体相变激活能最低,马氏体变体间界面的可动性好,形状记忆效应最佳。
