Analysis on Test Method of Metal Magnetic Memory Mechanism of Ferromagnetic Materials Based Plastic Deformation

Abstract:

A new test method of metal magnetic memory (MMM) was designed and was applied to study the relationship between MMM signals distortion and uneven plastic deformation so as to obtain the direct evidence of the result that MMM signals change unevenly causing by the unevenly plastic deformation in tensile test. Macro magnetic memory measurement were done to capture the occurrence time and position of MMM signals’ distortion during the period of plastic deformation, strain measurement were done before each MMM measurement and micro slip lines were observed after each time when MMM signals were measured to capture the occurrence time and position of plastic deformation. Then direct evidence can be obtained by compared the consistency of the time and positions. Preliminary tests were done to prove the rationality and feasibility of the new test method. The results show that the evidence can be obtained effectively and change law of MMM signals were reproduced by this new test method.
