Effect of barothermal processing on the structure and properties of a WC-Ni3Al alloy
Source abstract
Abstract
We have studied the effect of barothermal processing (BTP) on the properties of samples prepared by sintering mixtures of tungsten carbide and aluminum nickelide powders (92 vol % WC + 8 vol % Ni 3 Al) in vacuum and hydrogen. X-ray diffraction data indicate that BTP influences the unit-cell parameters of the WC and improves the mechanical properties of the alloy. In particular, it increases its fracture toughness, bending strength, compressive strength, and fracture work. BTP at 1450°C and 150 MPa produces the most significant changes in the properties of the alloy.
