The process of adding ìtrio the stainless steel alloys cast by centrifugation, for application in high temperature, alloy and product made with them

摘要

b report describing the invention "process for the addition of u00ectrio the stainless steel alloys cast by centrifugation for application at high temperatures.Alloy and product made with them " d are stainless steel alloys with the addition of u00ectrio from adding to the bath of a ternary composition fe4y2si9 and consequent formation ofA phase non stoichiometric composition yxniysiz.The control conditions of raw material, temperatures of the oven, time and order of addition of microconstituu00edntes leakage and promote an alloy with high estabildade metallurgical.The alloys obtained the greatest breakthrough time for fluency, better resistance to oxidation and lower intervu00e1 him temperature variation liquidus - solidus.
