研究了脉冲磁场对1Cr18Ni9Ti奥氏体不锈钢显微组织的影响。实验结果表明，在1Cr18Ni9Ti奥氏体不锈钢凝固过程中，脉冲磁场的施加能显著细化其组织。在一定的磁场强度下，晶粒尺寸达到最佳。此外，脉冲磁场的应用可以显著缩短凝固时间，并导致起凝和终凝温度的升高。
The aim of this paper is to investigate the effects of pulsed magnetic field on the microstructure of 1Cr18Ni9Ti austenitic stainless steel. Experimental results indicate that during the solidification of 1Cr18Ni9Ti austenitic stainless steel, applications of pulsed magnetic field can significantly refine its microstructure. And there is an optimal value of magnetic intensity under which the grain size is the finest. Moreover, applications of pulsed magnetic field can significantly reduce the solidification time, and also lead to increase of the initiation and finishing solidification temperature.
