For this purpose, milled powders with composition of Ni-20.9Al-8Cr-0.49B (% at.) with and without the addition of 10% in volume fraction of chromium particles have been produced. Both alloys were consolidated by hot isostatic pressing (HIP). After HIP, heat treatment was applied to homogenize the microstructure. The chromium reinforcement has an important effect in the yield strength and ultimate strength increase. The reinforced alloy presents a yield strength of 1300 MPa at room temperature with respect to 800 MPa for the un-reinforced material. After heat treatment, the yield strength of both alloys does not change significantly. However, a decrease in ductility and ultimate tensile strength have been observed}, number={4}, journal={Revista de Metalurgia}, author={García-Barriocanal, J. and Garces, G. and Pérez, R. and Adeva, P.}, year={2005}, month={Aug.}, pages={286–291} }
