前言在近代航空、航天、原子能等尖端科学技术中的发动机制造方面,对结构件特别是一些精密连接件,要求利用钎焊来解决连接问题,而钎焊料的研制则是首先应解决的重要课题。因此,我们从七十年代末期开始,对镍基钎料进行了研究,现将研制情况介绍
Preface In modern aviation, aerospace, atomic energy and other cutting-edge science and technology engine manufacturing, the structural parts, especially some precision connectors, requires the use of soldering to solve the connection problem, and the development of solder is the first important Question. Therefore, we started from the late seventies, nickel-based solder has been studied, the development of the introduction
