EFFECT OF THE COMPOSITION ON THE ELASTIC PROPERTIES OF BINARY NICKEL ALLOYS (in Ukrainian)
The effect of the composition on the elastic properties of a number of systems with a nickel base (nickel--chromium; nickel-- molybdenum; nickel -- titanium; nickel -- aluminum) was studied. The coefficients of thermal expansion of the investigated nickel alloys were determined. lt was found that on adding chromium or molybdenum to nickel the modulus of elasticity increased, while on alloying with titanium or aluminum the modulus of elasticity was only slightiy altered. The Debye temperature for nickelchromium, nickel-titanium, and nickel- aluminum alloys was detemined by Young's modulus data. The Debye temperature, calculated from elasticity constants, changed slightly on alloying. It was established that the ratio of the temperature coefficient of thermal expansion to the temperature coefficient of the modulus of elasticity for nickelmolybdenum and nickel-titanium alloys in a definite temperature region is approximately constant. Hence the temperature coefficient of the modulus of elasticity may be approximately determined by the thermal expansion coefficient of the alloy. (auth)
