LONG-TERM RUPTURE STRENGTH OF ALLOYS AND PLASTICS FROM TENSILE STRENGTH AT ELEVATED TEMPERATURES.

Abstract

The report covers an investigation to determine if the long-term tensile stress-rupture strength of alloys could be calculated from the results of static tensile strength tests at elevated temperatures. Twenty-one alloys were investigated. A second-order form of a mechanical-chemical equation of state was used to draw master rupture curves from both long-term rupture and tensile strength data. It was concluded that the long-term strength of an alloy could be computed from a knowledge of its tensile strength at elevated temperatures, chemical composition, and mode of failure. (Author)
