Abstract

The invention relates to a rare earth magnesium alloy metallographic corrosive and application thereof. The rare earth magnesium alloy metallographic corrosive is composed of chlorate, boric acid and the following components in parts by volume: 16-24 parts of glycerinum, 50-70 parts of absolute ethyl alcohol and 14-26 parts of distilled water. The corrosive can be used for preparing high-quality metallographic pictures of magnesium alloys with different rare earth contents, and convenience is provided for subsequent analysis of the relationship between the alloy structure and the performance. The method is easy to operate, the requirement for laboratory conditions is not high, time is saved, the labor intensity is low, few consumables are used, and the efficiency is high.

Description

technical field [0001] The invention relates to a rare earth magnesium alloy metallographic etchant and application thereof, belonging to the field of metallographic sample preparation. Background technique [0002] The microstructure of the alloy determines the performance. In the process of developing new rare earth magnesium alloys, it is necessary to observe and analyze the microstructure of the magnesium alloy to understand the influence mechanism of the microstructure of the alloy on the macroscopic properties, and then through the element content of the alloy, Type, heat treatment process and other means to improve the alloy structure, and then improve the macroscopic properties of the alloy. Metallographic microscopy is one of the most widely used methods in material research and inspection due to its simplicity, low price, high efficiency and practicality, and wide field of vision. On the one hand, due to the low hardness and soft quality of magnesium alloy, it is ...
