Preliminary Study on Porous High-Manganese 316L Stainless Steel Through Physical Vacuum Dealloying

In this study, porous stainless steel was prepared successfully by physical vacuum dealloying method. The based alloy is high-manganese 316L-50Mn alloy. The porous high-manganese 316L stainless steel showed a three-dimensional continuous porous structure with 1-2 ktm pore size. Temperature was the k...

Zusammenfassung:In this study, porous stainless steel was prepared successfully by physical vacuum dealloying method. The based alloy is high-manganese 316L-50Mn alloy. The porous high-manganese 316L stainless steel showed a three-dimensional continuous porous structure with 1-2 ktm pore size. Temperature was the key factor for the physical dealloying process to produce porous stainless steel, and the optimized treatment temperature was between 800 and 850 ~C for the high- manganese 316L-50Mn alloy.
