DEVELOPMENT OF RESISTANCE STRAIN GAGES USABLE UP TO 1600 F. Period Covered, June 21, 1955 to June 21, 1956
Abstract
Developmental work on a quasi-static high temperature strain gage to measure large strains in the temperature range 1000 to 1600 deg F is reported. Refractory single phase alloys with Fe, Co, and Ni bases were selected for exploration as strain gage wires. Besides good oxidation resistance it was aimed to achieve a low temperature coefficient of resistance and matching expansivity with the chosen base material. The solid solution alloys of the FeCr-Al composition approached most closely the ideal requirements for high temperature strain gage wires. Several alloys in this group were vacuum melted and the hot and cold forming properties were determined. Fe-25 Cr-5 Al, Fe-25 Cr-7.5 Al, and Fe-20 Cr-10 Al alloys ultimately were drawn into 0.001 in./0.002 in. diameter wires. Strain gages fabricated from these wires were cemented to Inconel test bars and preliminary gage calibrations were made at elevated temperatures. (auth)
