Effect of pulsed magnetic field on microstructure of 1Cr18Ni9Ti austenitic stainless steel

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.
