Notes:
This work presents the possibility of obtaining duplex stainless steels through powdermetallurgy technology starting from austenitic X2CrNiMo17-12-2, martensitic X6Cr13 powders bycontrolled addition of alloying elements, such as Cr, Ni, Mo, Cu in the right quantity to obtain thechemical composition of the structure similar to biphasic one. Moreover the ferritic stainless steelX6Cr17 has been mixed to austenitic stainless steel in the ratio of 50%-50% in order to exam thederiving structure after sintering. In the studies behind the preparation of mixes, Schaffler’s diagramwas taken into consideration. Prepared mixes of powders have been compacted at 800 MPa andsintered in a vacuum furnace with argon backfilling at 1260°C for 1 hour; after sintering rapidcooling has been applied in N2
