Abstract
AbstractUsing alloys whose initial microstructures are composed of Ni3Si(L12), Ni3Si(L12)+Ni3Ti(D024) and Ni3Si(L12)+Ni3Nb(D0a), aging phenomenon and the associated high-temperature tensile property were investigated. It was shown by micro hardness measurement that age hardening behavior due to the precipitation of the Ni3Ti(D024) phase occurs in all alloys at temperatures above 823K. It was however shown by tensile test that the precipitated Ni3Ti(D024) phase is not so much effective in improving the mechanical properties of alloys whose initial microstructures are composed of Ni3Si(L12)+Ni3Nb(D0a) or Ni3Si(L12)+Ni3Ti (D024). In alloys whose initial microstructures are composed of Ni3Si(L12)+Ni3Nb (D0a), a good combination of tensile strength and tensile elongation was found over a wide of test temperature whether or not they contain the precipitated Ni3Ti(D024) phase.
