Title:
MANUFACTURE OF HIGH TEMPERATURE GAS COOLING REACTOR TEMPER MATERIAL AND ALLOY THEREFOR
Document Type and Number:
Japanese Patent JPS58157937
Kind Code:
A
Abstract:
A method and alloys for fabricating wrought components of a high-temperature gas-cooled reactor are disclosed. These wrought, nickel-based alloys, which exhibit strength and excellent resistance to carburization at elevated temperatures, include aluminum and titanium in amounts and ratios to promote the growth of carburization resistant films while preserving the wrought character of the alloys. These alloys also include substantial amounts of molybdenum and/or tungsten as solid-solution strengtheners. Chromium may be included in concentrations less than 10% to assist in fabrication. Minor amounts of carbon and one or more carbide-forming metals also contribute to high-temperature strength.
