Alloys and Ceramic Materials for High-Temperature Service

Abstract

A creep test was conducted on a GT-45 alloy for 1630 hours. Minimum creep rate was 0.000017 percent per hour. Nine 60Cr-15Fe-25Mo alloy heats were melted in vacuum apparatus. Small amounts of manganese decreased shock sensitivity and improved properties of this material. Physical properties of No. 38900 Alundum ceramic specimens, burned at 1000 to 2250 deg F, were approximately same. Appreciable shrinkage, increase in bulk density, and decrease in water absorption were noted when specimens were burned at 2500 deg F.
