Abstract
Abstract In this paper, the effect of thermomagnetic treatment (TMT) on the magnetic and mechanical properties of the cold-rolled Fe-Cr-Co alloy was investigated. For this purpose, an alloy with Fe-23Cr-9Co chemical composition was prepared by vacuum induction melting. Then, the cast ingots were subjected to hot forging. The homogenization treatments were performed on the forged samples at 1200 °C for 10, 60, 120, 240 min. Then, the homogenized samples were cold-rolled to 40% and 80% reduction in area. The cold-rolled samples were annealed under the magnetic field at different temperatures and holding times; subsequently, they were aged. The results showed that the best mechanical and magnetic properties could be achieved under these conditions: thermomagnetic treatment at 640 °C for 45 min and step-aging from 620 °C to 500 °C. Under these conditions, the samples had the coercivity and saturation magnetization of 77 Oe and 158 emu/gr, respectively; also, the ultimate tensile strength and elongation of them were 1050 MPa and 12%, respectively.
