1.引言虽然已经报道了Mn-Cu系平衡相图的大量研究,作者引用1969年Shunk提出的如图1所示的作为参考。在大量的关于这种合金物理性能研究中,Street等1959报导了含80％和85％锰的Mn-Cu合金(由刚好低于熔点的Υ相淬火)杨氏模量的温度变化。根据他们的结果,分别在280°K和340°K发现合金杨氏模量的最小值,这两个温度与后来Basinski等和Bacon等提倡
1. INTRODUCTION Although a large number of studies have been reported on the equilibrium phase diagram of Mn-Cu system, the author refers to Shunk’s proposed in 1969 as shown in FIG. 1 for reference. In a large amount of research on the physical properties of this alloy, Street et al. 1959 reported temperature changes in Young’s modulus of Mn-Cu alloys containing 80% and 85% manganese (quenched from the γ phase just below the melting point). Based on their results, the minimum Young’s modulus of the alloy was found at 280 ° K and 340 ° K, respectively, which are consistent with what was later proposed by Basinski et al. And Bacon et al.
