高铝钛镍基合金晶粒度的研究

STUDY ON THE GRAIN FINENESS OF HIGH TEMPERATURE ALLOY STEELS CONTAINING HIGH ALUMINIUM TITANIUM AND NICKEL

研究了对高温镀镍基高温金晶粒度的影响因素。以便减少晶粒度不合格废品 ,结果表明 ,在冶炼工艺和变形量一定的条件下 ,碳含量。

In order to reduce the defect of grain fineness,the factors that influence the grain fineness of high temperature alloy steels containging aluminium,titanium and inckel were studied in this paper.The research showed that carbon content,reheating time in high temperature zone and finishing rolling temperature were main factors to influence the grain fineness in the condition of the same smelting processes and the same deformation of rolling.
