Effect of annealing temperature on the mechanical properties and magnetic properties of 00Cr13Si2Al steel
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.
