Abstract

Early in its investigation of a strain gage for use in measuring static strains at temperatures up to 1600 F, the Aeronautical Structures Laboratory found that gage performance was limited by the temperature characteristics of the commercial alloys employed as the sensing element. Accordingly, a program was sponsored at the Armour Research Foundation for the development of a superior strain-sensing alloy. Some of the results of this program are reported in this symposium by workers at the Armour Research Foundation. The most promising of the alloys developed appeared to be alloy D which has a nominal composition of 70 per cent iron, 20 per cent chromium, and 10 per cent aluminum.
