Stress-controlled fatigue of HfNbTaTiZr high-entropy alloy and associated deformation and fracture mechanisms

Shuying Chen et al.

Summary: In this study, stress-controlled fatigue tests were conducted to investigate the fatigue behavior of an alloy. The results showed excellent fatigue resistance in the high-cycle regime due to delayed crack initiation and good resistance to crack propagation in the low-cycle regime. The alloy exhibited higher fatigue strength compared to other high-entropy alloys and several structural alloys, such as steels, titanium alloys, and aluminum alloys. The stochastic nature of the fatigue data was effectively captured using a 2-parameter Weibull model.

Factors determining solid solution phase formation and stability in CoCrFeNiX0.4 (X=Al, Nb, Ta) high entropy alloys fabricated by powder plasma arc additive manufacturing

Yupeng Zhang et al.

Summary: The formation of solid solution phase in high entropy alloys (HEAs) is influenced by factors such as mixing entropy, mixing enthalpy, atomic radii, and atomic size difference. Other factors like electronegativity, valence electron concentration, and melting point also play a significant role. This study investigated the microstructural evolution of CoCrFeNiX0.4 HEAs with equi-atomic radii element additions (Al, Nb, Ta) prepared by powder plasma arc additive manufacturing (PPA-AM), revealing variations in phase formation and mechanical properties.

High-Entropy Alloys for Advanced Nuclear Applications

Ed J. Pickering et al.

Summary: High-entropy alloys (HEAs) offer expanded compositional freedom for advanced nuclear applications, but our understanding of their irradiation responses is still in its infancy. While some studies suggest special irradiation damage resistance in HEAs, proposed mechanisms like sluggish diffusion and lattice distortion are not universally convincing, and unique differences in HEAs compared to conventional alloys may lie in factors like poor thermal conductivities.

Summary: This study captured the dynamic interaction between LCFs and dislocations in ductile BCC HfNbTiZr HEAs, demonstrating how LCFs influence strength and ductility by promoting dislocation interaction.
