一、前言高温金相显微镜是冶金科学领域内新的重要研究工具之一。它是由高温台及其辅助装置、真空系统和金相显微镜等组成,用来直接观察金属及合金在高温时的组织和变化。在这一实验工具未发展之前,只能用间接的方式把某些金属及合金在高温时的组织“固定”在常温下进行观察,但不能观察到连续的变化过程,而这些过程正是反映了金属及合金某些最重要的特性,因此,运用这一实验工具在高温下进行直接的观察和研究将具有理论与实践的双重意义。以往,曾向国外购入高温台,其加热形式大都为间接 I. Introduction High-temperature metallurgical microscope is one of the important new research tools in the field of metallurgy. It is composed of high temperature stage and its ancillary equipment, vacuum system and metallographic microscope, etc., used to directly observe the metal and alloy at high temperatures, the organization and changes. Before the development of this experimental tool, only some of the metals and alloys can only be indirectly “fixed” at high temperatures observed at room temperature, but can not observe the continuous process of change, and these processes are reflected Some of the most important properties of metals and alloys, therefore, the use of this experimental tool for direct observation and research at high temperatures will have the dual significance of theory and practice. In the past, high-temperature Taiwan has been purchased from abroad, most of its heating form indirect
