As-Cast Microstructure and Mechanical Properties of a New Superalloy

Conference paper

Abstract

In this paper, we have investigated the as-cast microstructure, mechanical properties and alloying elements of Ni-11.5Cr-3.0Mo-2.0Al-1.0Nb-0.4Ti-0.05C alloy. The results indicated that the microstructure of the alloy are mainly composed by γ phase, γ′ phase and carbides. With increasing temperature to 760 °C, the strength and plasticity of the alloy decreased obviously. In addition, as the contents of alloying elements in the alloy like Al, Mo, Nb and Ti are increased, the microstructure of the alloy don’t change obviously, but a increase of tensile strength is obtained at room temperature and the plasticity decreased about 0.5%.
