Ma, T. Wu, L. Zhao] This paper describes the development and evaluation of temperature-compensated resistance strain gages for use to 800°C. These gages included single-element gages and double-element half-bridge gages. The filament of single-element gages was fabricated from specially developed Fe−Cr−Al−V−Ti−Y alloy wire. When bonded to high-temperature Ni-based alloy GH39 after stabilization at 800°C for one hour, the apparent strain from room temperature to 800°C was less than 2000 μm/m. Double-element gages were fabricated from Pt−W−Re−Ni−Cr−Y alloy wire (active grid) and Pt−Ir alloy wire (compensating grid). When bonded to different high-temperature alloy specimens and stabilized, and when ballast resistance in series with the compensating grid adjusted suitably, the gages' apparent strains from room temperature to 800°C were less than 2400 μm/m. Effects of preoxidization of Fe−Cr−Al wire on the characteristics of the single-element gages are described. Society for Experimental Mechanics, Inc., 1990 Ma L.
