چکیده انگلیسی
Despite, the homogeneous and refined microstructure, spray-formed deposits of binary Fe-Si alloys with high silicon content are still difficult to hot/cold roll due to A2-disordered/B2-ordered reactions. The addition of aluminum to Fe-Si alloys may be able to keep the A2-disordered phase metastable at temperatures below 973Â K, allowing the deposits to be rolled without cracking while adequately maintaining their magnetic properties. This study is a first attempt to investigate the microstructure and the magnetic properties of spray-formed Fe-3Â wt.%Si-3.5Â wt.%Al alloy. Argon and nitrogen were used as atomization gases. The addition of aluminum to Fe-Si alloys led to the successful production of thin sheets (0.5Â mm thickness) from spray-formed deposits when using argon as atomizing gas. In contrast, the use of nitrogen led to the formation of AlN particles, resulting in excessive brittleness of the spray-formed deposit, which fractured during cooling to room temperature. Otherwise, the magnetic properties of the Fe-3.0Â wt.%Si-3.5Â wt.%Al alloy performed very well when compared with binary Fe-6.5Â wt.%Si, especially when spray formed with argon.
