摘要

本文详细叙述铝—镁合金膜的蒸发工艺

介绍观察和测定合金膜成份、结构和机械性能的方法和实测结果。由实测得出铝-2%镁合金膜的机械性能优于纯铝膜(抗噪声破坏能力

铝膜是131db

铝-2%镁合金膜是137db。当频率为50—150Hz时

可承受的振动峰值加速度

铝膜为5g

铝-2%镁合金膜是7g)。分析膜的成分和结构得知

原因在于铝-2%镁合金膜是α相的固溶体和α相的过饱和固溶体结构。

Abstract

This paper describes the preparation technology of aluminium-magnesium alloy film in detail

and gives the test reults and methods for observation and measurement of mechanical performance

structurs and composition of the alloy film. We have found that the mechanical performance of aluminium-2% magnesium alloy film is better than that of alumlnium film through experiments. (The cpability of antl-nolse destruction is 131 db for aluminium film while 137 db for film Al-2% Mg alloy film. As regarding the cepcbility of antl-vlbratlon destruction

when frequency is 50-150Hz the peak amplitude of acceleration which the film can bear is 5fi for A1 film and 7g forAl-2% Mg alloy film). The reason for its’ fine performance from analysis of the composition and structure is that Al-2% Mg alloy film is a phase solid solutiion

α phase supersaturated solid solution structure.
