Design Data for Alloy 282 High Temperature Concentrating Solar Power Components

Abstract

New design rules for high temperature concentrating solar power metallic components have been proposed recently. These rules are to be used in conjunction with the Section III, Division 5 rules of the ASME Boiler & Pressure Vessel Code and include three design by analysis options. In this paper, we report the corresponding design data for a nickel-based high temperature alloy – Alloy 282. The current Alloy 282 Code Case includes some basic material properties such as Young’s modulus, Poisson’s ratio, thermal properties, yield strength, tensile strength, and allowable stress S_o. However, a complete design check for high temperature components requires additional material data including allowable stress S_m, isochronous stress-strain curves, minimum-stress-to-rupture, fatigue diagrams, and creep-fatigue damage envelope. We construct these design data from the available material data in the literature and data generated recently at Idaho National Laboratory. We also develop an inelastic constitutive model for use with the design by inelastic analysis method.
