本文研究了固溶温度、时效温度、冷变形对18Ni(350)马氏体时效钢室温和高温磁滞性能的影响。结果指出,材料高温磁滞性能下降的主要原因是热骚动力的增大和部分铁磁性奥氏体在高温下变为顺磁性。提高固溶温度使材料的磁滞性能提高。采用冷变形在晶体内产生一定的织构和增加的效后金属化合物的数量及弥散度,使基体贫Ni,而控制逆转变奥氏体的大小。分布和数量,改善了磁滞性能。
In this paper, the effects of solution temperature, aging temperature and cold deformation on the room temperature and high temperature hysteresis of 18Ni (350) martensitic steel were studied. The results show that the main reason for the decrease of high temperature hysteresis properties of materials is the increase of thermal power and the partial conversion of ferromagnetic austenite to paramagnetic at high temperature. Increasing the solution temperature increases the hysteresis of the material. The use of cold deformation in the crystal to produce a certain texture and increase the number and dispersion of the effective metal compounds, so that the matrix poor Ni, and control the size of reverse austenite. Distribution and quantity improve hysteresis performance.
