Two-pin magnetic probe layering detection system for residual austenite content

Abstract

The invention discloses a two-pin magnetic probe layering detection system for a residual austenite content. The detection system can achieve layering detection of the residue austenite content, and has characteristics of high detection precision, low detection difficulty, short detection period, and simple and flexible detection method. The detection system is capable of reaching any part of a ferromagnetic material object to be detected and achieving nondestructive detection of the material.

Description

technical field [0001] The invention relates to the retained austenite of ferromagnetic materials, more specifically a two-legged magnetic probe layered measurement system suitable for the retained austenite of ferromagnetic materials. Background technique [0002] Austenite is a phase of iron, another common phase is martensite. Retained austenite refers to a small amount of untransformed austenite after martensite transformation. [0003] A large number of engineering practices have proved that retained austenite has an important influence on the mechanical properties, physical properties and process properties of materials. An appropriate amount of retained austenite can improve toughness, resistance to contact fatigue and low temperature toughness, and reduce structural stress and quenching deformation. However, excessive retained austenite will reduce hardness and wear resistance. Especially for some parts with high requirements on size and stability, measuring tools...

Problems solved by technology

However, in the traditional sense, it is difficult to detect the residual austenite content of a certain layer of the material, and the detection is difficult, the detection cycle is long, the detection cost is high, and the test method is inconvenient.
