Tungsten Concentration

WxNbMoTa refractory high-entropy alloys with four different tungsten concentrations (x = 0, 0.16, 0.33, 0.53) were fabricated by laser cladding deposition. The crystal structures of WxNbMoTa alloys are all a single-phase solid solution of the body-centered cubic (BCC) structure. The size of the grains and dendrites are 20 μm and 4 μm on average, due to the rapid solidification characteristics of the laser cladding deposition. These are much smaller sizes than refractory high-entropy alloys fabricated by vacuum arc melting. In terms of integrated mechanical properties, the increase of the tungsten concentration of WxNbMoTa has led to four results of the Vickers microhardness, i.e., Hv = 459.2 ± 9.7, 476.0 ± 12.9, 485.3 ± 8.7, and 497.6 ± 5.6. As a result, NbMoTa alloy shows a yield strength (σb) and compressive strain (εp) of 530 Mpa and 8.5% at 1000 °C, leading to better results than traditional refractory alloys such as T-111, C103, and Nb-1Zr, which are commonly used in the aerospace industry.

Laser cladding CoCrFeNiTiNbB1.25 high-entropy alloys coatings on H13 steel was fabricated. The microstructure and abrasion resistance of aged high-entropy alloys coatings at different temperature were researched. Results showed the phase was not changed in the high-entropy alloys coatings as the aging temperature elevated, the volume fraction of TiB phase was firstly increased, then reduced. The diffraction peak of fcc phase was firstly shifted to the right, and then shifted to the left. The aged high-entropy alloys coatings consisted of typical dendrite, interdendritic eutectic and dispersed intermetallic compound, and the dendrite obviously was coarsened after aging at 850 °C. Compared with non-aged high-entropy alloys coatings, the microhardness of aged high-entropy alloys coatings was firstly elevated as the aging temperature elevated, then decreased, and the mass loss was opposite. The microhardness and mass loss was decreased by 4.3% and 11.9%, respectively, for the aging at 750 °C. The abrasion mechanism of non-aged high-entropy alloys coatings was the abrasive wear, and was the abrasive wear and adhesive wear after aging.
