| titleOfInvention | A kind of etchant for displaying undissolved high alloy phase in steel and metallographic display method |
| abstract | The invention relates to an etchant for displaying an undissolved high alloy phase in steel and a method for displaying the undissolved high alloy phase. The etchant comprises ferric chloride with a mass percentage of 1-5%, and a Alkanolamide, 0.2-1% sodium dodecyl benzene sulfonate, the balance is ethanol, the display method is to cut and pre-treat the steel sample to be tested, immerse it in the corrosive agent for corrosion, and then rinse and blow Dry, put it into a metallographic microscope for observation, the results show that the etchant can selectively display the high chromium and manganese undissolved high alloy phases in the steel, and the tempered martensite, sorbite, ferrite, etc. are all corroded to form Brown-black background, high contrast, simple and fast process operation, suitable for quantitative analysis of metallographic structure. |
