主 题:pulse current austenitic stainless steel solidification structure
摘 要:The 1Cr18Ni9Ti specimens were treated respectively with pulse current under 520 V and 2 600 V during solidification and the solidification structure was *** results showed that pulse current can refine solidification grains,cut primary dentrities remarkably and reduce second dentritic arm *** mechanism and effect are changed with operation parameters.
