Some Experiments on the Fe-Cr-Al Electric Heating Wires

Kiichiro Shinzi


Abstract:

The effects of Cr, Al, C, Si and Mn on the properties of Fe-Cr-Al electric Leating wires were investigated. The effects of Al and Si on erectric resistance were most remarkable and oxidation resisting property was improved by Cr, Al and Si. The properties of cold working were improved by rapid cooling after soft annealing. This is explained from the relations between the solid solubility of (CrFe)4C to α solid solution and temperature. Ta was most effective to prevent the grain growth of wire caused by heating at high temperature and secondly Zr, Ti and V were effective.
