一种用于钢的显微组织演化的原位追踪金相分析方法
摘要：
本发明提供一种用于钢的显微组织演化的原位追踪金相分析方法：将显微压痕硬度实验与光学金相分析相结合，利用硬度压痕作为观察定位标记与金相照片定位标记，实施“金相观察与拍照、真空保护、热处理、抛光、金相侵蚀”的反复操作，获得所关注的显微组织的原位追踪金相照片，从而实现显微组织演化过程的原位追踪金相分析。本发明为一种适用范围广、操作简单并且可靠性高的实验方法。
摘要（英）：

The invention provides an in-situ tracking metallographic analysis method for microstructural evolution of steels and the method comprises the following steps of: combining a microscopic indentation hardness experiment and an optical metallographic analysis, taking a hardness indentation as an observation positioning mark and a metallograph positioning mark, implementing repeated operation of metallographic observation and photographing, vacuum protection, heat treatment, polishing and metallographic erosion, and obtaining in-situ tracking metallographic photographs of concerned microscopic structures, thereby implementing in-situ tracking metallographic analysis of a microstructure evolutionary process. The in-situ tracking metallographic analysis method for the microstructural evolution of the steels provided by the invention is an experimental method which is wide in range of application, high in reliability and simple to operate.
