HIGH-TEMPERATURE STRENGTH AND PHYSICOCHEMICAL PROPERTIES OF MULTICOMPONENT NICKEL ALLOYS,
Abstract
A study was done on the heat resistance and physico-chemical properties of nickel alloys with compositions ranging from two to eight components. Alloying was done with 10% (by weight) chromium, 2% titanium, 6% tungsten, 3% molybdenum, 2% niobium, 5% cobalt, and from 0 to 12% aluminum. Before testing, the alloys were fully annealed to maximize the precipitation of the y'-phase. The effect of the y'-phase on the physico-chemical properties and heat resistance of the alloys was measured by electron microscopy, x-ray analysis, electrical conductivity, thermal expansion, microhardness, and rupture time at 900C and 12 kg/sq mm.
