ABSTRACT This overview paper describes the interaction of powder metallurgical iron-base alloys with the atmosphere during sintering. The methods of thermal analysis serve to clarify the processes that take place especially during the heating stage of the sintering cycle. After a discussion of the physical and chemical fundamentals of the sintering process, the methods of thermal analysis are explained. The differences between plain iron and alloyed systems are discussed in detail. Classical PM low alloy steels with alloying elements, such as Cu, Ni and Mo, react in a similar way as unalloyed carbon steels. The situation changes dramatically, when oxygen sensitive elements as chromium, manganese and even more silicon come into play. The removal of the surface oxygen is much more crucial, and there are several competing reactions, which have to be considered when these systems should be sintered in industrial scale to reach the desired mechanical and dimensional properties.

烧结过程中铁粉压块与气氛之间的反应——概述

摘要 这篇综述论文描述了粉末冶金铁基合金在烧结过程中与大气的相互作用。热分析方法有助于阐明特别是在烧结循环的加热阶段发生的过程。在讨论了烧结过程的物理和化学基础之后，解释了热分析方法。详细讨论了纯铁和合金系统之间的区别。含有合金元素（例如 Cu、Ni 和 Mo）的经典 PM 低合金钢的反应方式与非合金碳钢类似。当铬、锰甚至更多的硅等氧敏感元素开始发挥作用时，情况就会发生巨大变化。表面氧的去除更为关键，有几个相互竞争的反应，
