引言我国在自然资源上具有与其他先进的工业国十分不同的特点,因此必须建立起适合于我国资源情况的新的合金系统,相应的也就必须进行一系列新的科学研究工作. 考虑到这些情况以及建立耐热合金系统的原则我们准备以铁-钨-矽系统作为今后研究的基础.为了便于展开工作首先研究了含钨9%的钢(成分接近P9).
INTRODUCTION China has quite different natural resources from other advanced industrial nations, and therefore it is necessary to establish a new alloy system that is suitable for the resources of our country and accordingly a series of new scientific researches must be carried out. As well as the principle of creating a heat-resistant alloy system We intend to use iron-tungsten-silicon systems as a basis for future research. In order to facilitate this work, we first studied the steel containing 9% tungsten (composition close to P9).
