【摘要】 本文研究了Cu-Al-Zn-Mn-Ni合金的伪弹性变形行为,并用金相和X射线衍射法观察分析了变形及时效前后马氏体组织结构的变化。结果表明,合金在母相状态时的伪弹性与其原始马氏体组织结构密切相关;通过改善原始马氏体组织结构的自协作性和适当的时效处理可以显著提高合金的伪弹性。更多还原

【Abstract】 The deformation behaviour of parent phase and the pseudo-elasticity were studied, and the variation of microstructure with aging and deforming was analyzed using optical microscopy and X-ray diffraction. The experimental results showed that the pseudoelasticity in parent phase state is closely related to the original martensite microstructures. The pscudoelasticity of the alloy can be considerably improved with the perfection of martensitic self-accommodation and proper ageing treatment.更多还原
