MAGNETIC PHASE TRANSFORMATION MATERIAL, MANUFACTURING METHOD OF MAGNETIC PHASE TRANSFORMATION MATERIAL AND USE OF MAGNETIC PHASE TRANSFORMATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a novel kind of magnetic phase transformation material having better mechanical characteristic and a method of preparing the magnetic phase transformation material.SOLUTION: There is provided a magnetic phase transformation material of the formula NiMnCoTi, where a+b+c=100, 20a≤90, 5≤b50, 5≤c≤30, 0≤m≤a, 0≤n≤b, 0m+na+b and any one or combination of a, b, c, m, n represent atom percentage content. The magnetic phase transformation material has characteristics such as high toughness, high deformation rate, ferromagnetic and magnetic field derived martensite phase deformation and capable of being used widely in various fields including high strength and high toughness actuator, temperature-sensitive and/or magnetosensitive element, magnetic field cooling device and magnetic field cooling equipment, magnetic heat pump device, magnetic memory, minute electronic mechanical device and minute electronic mechanical system.SELECTED DRAWING: Figure 3
