The effect of composition and transformation time on the heat resistance of alloys was investigated by testing the creep of Ni-Cr-W-Ti-Al alloys (with contents of Al and Ni from 0 to 7.9% and constant Cr, W, and Ti) at 1150 deg C for 7 hours in air. Tests were also made at 900 deg C with an initial loading of 6 kg/mm/sup 2/ for 10,000 and more hours, and constitution diagrams were plotted. The maximum heat resistance was found with alloys having 4.5 to 5.5% Al. The heat resistance maxima on isothermal constitution diagrams (composition-heat resistance) show variations with temperature as well as with time. (R.V.J.)
