摘要
对不同温度退火后00Cr13Si2Al钢力学性能和磁性能的变化进行研究.借助倒置金相分析系统(GX53)测量了退火试样的显微组织,计算不同温度下的平均晶粒尺寸,并利用MATS-2010D软磁直流测量装置测量试样的磁性能.结果表明,850～900 ℃的退火温度范围内,保温3 h后该钢具有较好的综合力学性能和磁性能,900 ℃室温强度为440 MPa,测试磁场分别为2 500 A/m、5 000 A/m、10 000 A/m时,磁感应强度为1.282、1.369、1.534,而1 000 ℃室温强度为435 MPa,磁感应强度为1.233、1.366、1.509.随着退火温度的升高晶粒尺寸增大,从而导致力学性能和磁性能的下降.
Abstract
The mechanical properties and magnetic properties of 00Cr13Si2Al steel after annealing at different tem-peratures were studied.The microstructure of annealed samples was measured using an inverted metallographic a-nalysis system(GX53),and the average grain size at different temperatures was calculated.The magnetic properties of the samples were measured using the MATS-2010D soft magnetic direct current measurement device.The results show that within the annealing temperature range of 850-900 ℃,the steel has good comprehensive mechanical and magnetic properties after 3 h of insulation.The room temperature strength at 900 ℃ is 440 MPa,and the magnetic induction strengths are 1.282,1.369,and 1.534 when tested with magnetic fields of 2 500 A/m,5 000 A/m,and 10 000 A/m,respectively.At 1 000 ℃,the room temperature strength is 435 MPa,and the magnetic induction strengths are 1.233,1.366,and 1.509.As the annealing temperature increases,the grain size increases,leading to a decrease in mechanical and magnetic properties.
