Abstract
The present invention relates to a kind of method of inspection of metallographic structure, specifically a kind of method of displaying austenite structure quickly and easily.According to technical scheme provided by the invention, the method for described displaying austenite structure quickly and easily comprises: grind the surface to be checked of stainless strip earlier with abrasive paper for metallograph, make the polishing scratch equilibrium on described surface to be checked, polishing scratch direction unanimity; With polishing cloth the surface of grinding is polished, after the polishing, described surface is observed under 100 power microscopes should not have obvious cut again; The drips of solution 1～50 that will prepare with dropper drips on the described surface after the polishing then, described surface is corroded, surface after corroding with soft fabric wiping again 5～6 seconds, dash with clear water at last and do, and clean with alcohol wipe, clean surface is placed on the tissue that microscopically is observed austenitic stainless steel.Utilize this method can check out the matrix of material in the short period of time.
Description
Technical field
The present invention relates to a kind of method of inspection of metallographic structure, specifically a kind of method of displaying austenite structure quickly and easily.
Background technology
In the production of cold-rolling stainless steel industry, often need the metallographic structure of check metal material, to determine the matrix in the metal material, the mechanical property that obtains to be scheduled to of composition and the technological parameter by the various alloying elements of suitable adjustment then.When check, generally adopt 10% oxalic acid aqueous solution electrolytic process, will immerse in the described oxalic acid aqueous solution through material surface after grinding, the polishing, after after a while, take out, be placed on the matrix that microscopically is observed material.There is following shortcoming in this method: 1, the instrument of Yao Qiuing is many; 2, with duration 3, need electricity consumption.Therefore, adopt this method to waste time and energy.
Summary of the invention
The objective of the invention is to design a kind of method of displaying austenite structure quickly and easily, utilize this method can check out the matrix of material in the short period of time.
According to technical scheme provided by the invention, the method for described displaying austenite structure quickly and easily comprises: grind the surface to be checked of stainless strip earlier with abrasive paper for metallograph, make the polishing scratch equilibrium on described surface to be checked, polishing scratch direction unanimity; With polishing cloth the surface of grinding is polished, after the polishing, described surface is observed under 100 power microscopes should not have obvious cut again; The drips of solution 1～50 that will prepare with dropper drips on the described surface after the polishing then, described surface is corroded, surface after corroding with soft fabric wiping again 5～6 seconds, dash with clear water at last and do, and clean with alcohol wipe, clean surface is placed on the tissue that microscopically is observed austenitic stainless steel; Described solution percent by volume is 36～38% HCl and 65～68% HNO
3Volume ratio by 1: 0.8～1.2 is mixed and made into.
Before grinding, stainless strip should be placed on the worktable and fix.
When grinding, carry out at least 3～5 times grinding with the abrasive paper for metallograph of different size from coarse to fine, during the abrasive paper for metallograph of a different size of every replacing, after once grinding direction should be different with previous grinding direction, after the polishing scratch that once grinds before must covering of the polishing scratch that once grinds.
The specification of described abrasive paper for metallograph is: 300 orders from coarse to fine, 500 orders, 800 orders, 1000 orders and 1200 orders; When carrying out grinding for 3 times, the specification of abrasive paper for metallograph is 300 orders from coarse to fine, 500 orders and 800 orders; When carrying out grinding for 5 times, the specification of abrasive paper for metallograph is 300 orders from coarse to fine, 500 orders, 800 orders, 1000 orders and 1200 orders.
Advantage of the present invention is: after utilizing method of the present invention, can in time understand stainless institutional framework, thereby adjust annealing process, to satisfy client's request for utilization.
