项目摘要

It has been accepted that it is difficult to control the coefficient of thermal expansion (CTE) because it inversely proportional to the melting point of materials. This study was aimed to develop a new method of controlling the CTE using phase transformation.It is known that plastically deformed alloys undergoing thermoelastic martensitic transformation can exhibit two-way shape memory effect, which is a reversible and spontaneous shape change during heating and cooling. The effect of the pre-deformation on the reversible shape change was quantitatively investigated in this study. It was found that the transformation hysteresis increases by cold-rolling and CTE【approximately equal】0 is obtained in Cu-Zn-Al alloy cold-rolled to 9% reduction. Although the one directional rolling causes anisotropy in CTE, two-dimensional low thermal expansion (LTE) can be obtained by a cross-rolling method. Moreover, the cold-workability is drastically improved in α+β two-phase alloys, which means that C … More u-Zn-Al Invar alloys possessing high electrical conductivity are promising for practical applications.The grain size is one of the important factors to control the thermal expansion property. It was found that higher reduction is required to obtain LTE in a large grain specimen, which was thermodynamically analyzed using the Clausius-Clapeyron relationship, leading to the establishment of a method of controlling the CTE of alloys. Single crystal experiments also clarified the mechanism of the LTE obtained in these new Invar alloys.The stability of Cu-Zn-Al Invar alloys was investigated. 500 thermal cycles between-190℃ and 90℃ hardly changed the thermal expansion property, and good thermal stability up to 80℃ was confirmed. Based on the results in this study, the Cu-based Invar alloys are being examined for applications particularly to a machine part in printers.It should be noted that several interesting results related to this study, including high damping capacity, improvement of fatigue properties and superplasticity, was obtained in the Cu-Zn-Al and Cu-Al-Mn alloys.

热膨胀系数(CTE)与材料的熔点成反比,因此很难控制。本研究旨在开发一种利用相变控制CTE的新方法。已知经过热弹性马氏体相变的塑性变形合金可以表现出双向形状记忆效应,即在加热和冷却过程中可逆和自发的形状变化。本文定量研究了预变形对可逆形状变化的影响。结果表明,冷轧后Cu-Zn-Al合金的相变滞后增大,CTE【近似等于】0;虽然单向轧制会导致CTE的各向异性,但通过交叉轧制方法可以获得二维低热膨胀(LTE)。此外,α+β两相合金的冷加工性能得到了显著改善,这意味着具有高导电性的C…More u-Zn-Al Invar合金具有广阔的应用前景。晶粒尺寸是控制热膨胀性能的重要因素之一。发现在大晶粒试样中需要更高的压下率才能获得LTE,并利用Clausius-Clapeyron关系对其进行了热力学分析,从而建立了控制合金CTE的方法。单晶实验还阐明了在这些新的因瓦尔合金中获得的LTE的机理。研究了Cu-Zn-Al因瓦尔合金的稳定性。在-190 ~ 90℃之间循环500次,热膨胀性能几乎没有变化,在80℃前具有良好的热稳定性。基于这项研究的结果,铜基因瓦尔合金正在研究应用,特别是在打印机的机器部件上。值得注意的是,在Cu-Zn-Al和Cu-Al-Mn合金中获得了与本研究相关的几个有趣的结果,包括高阻尼能力,改善疲劳性能和超塑性。少
