一、前言本文主要叙述一些典型钹青铜零件的变形问题,通过试验对几种防止铍青铜零件时效变形的方法做了进一步验证和比较。并结合本厂的生产实践找到了一种对尺寸大、形状复杂、不适于用夹具的零件防变形效果明显的新方法。 I. Preface This article mainly describes the deformation of some typical cymbals bronze parts, and further verifies and compares several methods to prevent aging deformation of beryllium bronze parts through experiments. And combined with the factory production practice to find a large size, shape complex, not suitable for parts with anti-distortion effect of the new method obvious.
