Method for producing reinforced platinum alloy and reinforced platinum alloy and glass manufacturing apparatus

摘要

Problem to be solved: to provide an oxide dispersion strengthened type reinforced platinum alloy capable of effectively avoiding damage such as cracking or the like which can occur when applied to a glass manufacturing apparatus.The present invention relates to an enhanced platinum alloy in which dispersed particles of an additive element oxide are dispersed in a matrix made of Pt or PtRh alloy.The enhanced platinum alloy contains Zr having an amount of 0.04 mass% or more and 0.25 mass% or less as an additive element, and the remainder comprises the constituent metal of the matrix and oxygen and inevitable impurities.The reinforced platinum alloy of the present invention is characterized in that the creep rupture time by the high temperature creep test of the stress of 10 MPa at 1400 ° C. is 100 hours or more, and the rupture elongation in the normal temperature tensile test is 35% or more.The present invention is a platinum based material having a proper balance between the strength and flexibility of the original.Diagram
