在金属学、热处理工艺及设备专业的“金属学”课程中,三元合金状态图是比较难进而又相当重要的一章。本文就本章教学问题谈几点个人体会,希望得到指正。一、关於三元合金状态图的教学目的熟悉并学会分析三元合金状态图,以理解三元合金的组织及组织转变过程,是学习三元合金状态图的基本目的。然而,这不是唯一的目的。如果深入一步体会,可以看出,学习三元合金状态图还是为了理解复杂合金的组织及组织转变过程。大家都知道,工业上实际使用的金属材料,多半是成分复杂的合金,要确切了解这些合金的成份——温度——组织间的关系,非常困难。通常是把复杂合金首先看成由其中两个主要组元构成的二元合金,然后再分别研究各个组元对合金的影响。但是,由于
In the “Methematics” course in metallurgy, heat treatment technology and equipment, the ternary alloy state diagram is a more difficult and rather significant chapter. This article talked about the teaching of this chapter a few personal experience, hope to be correct. First, on the ternary alloy state diagram teaching purpose Familiar with and learn to analyze ternary alloy state diagram to understand the ternary alloy organization and organizational transformation process, is the basic purpose of learning the ternary alloy state diagram. However, this is not the only purpose. If you take a deep step forward, you can see that learning the ternary alloy state diagram is also to understand the complex alloy organization and organizational transformation process. As we all know, the actual industrial use of metal materials, mostly complex alloys, to understand exactly the composition of these alloys - temperature - the relationship between organizations, very difficult. Usually, the complex alloy is first regarded as a binary alloy composed of two main components, and then the influence of each component on the alloy is studied separately. But due to
