The comprehensive utilization of the excellent magnetic properties and advanced catalytic ability Fe-based amorphous alloys (FAAs) is reported for first time. A novel Fe63Cr5Nb4Y6B22 (at%) alloy that has ferromagnetic to paramagnetic transition near room temperature good performance methylene blue degradation successfully synthesized. applicable automatically recycled dye with its thermal-tuning behavior. When an external wastewater applied (high temperature), FAAs are disperse into water...
Metallic materials are mostly susceptible to hydrogen embrittlement (HE), which severely deteriorates their mechanical properties and causes catastrophic failures with poor ductility. In this study, we found that such a long-standing HE problem can be effectively eliminated in the Fex(CrCoNi)1-x face-centered-cubic (fcc) high-entropy alloys (HEAs) by triggering localized segregation of Cr at grain boundaries (GBs). It was revealed increasing Fe concentration from 2.5 25 at. % leads...
We found boron doping can substantially reduce the ductility-loss in CrCoNi medium-entropy alloy after gas-hydrogen charging, from ∼71% to ∼46%, while fracture mode transfers predominantly intergranular ductile transgranular dominated. The two alloys have no difference phase-structures (single face-center-cubic), grain sizes, and grain-boundary (GB) characters. However, atom probe tomography identified apparent GB decoration of up 1.5 at.% nanometer-scaled scattered borides boron-doped...
Scan speed impacts greatly on average temperature variation rate and thus atomic-level changes in clusters crystallization.
Structural materials with higher melting temperatures and better mechanical properties than superalloys are in high demand refractory applications. A promising WReTaMo high‐entropy alloy (RHEA) strength at 1600 °C is fabricated by vacuum arc melting. The RHEA has a body‐centered cubic (BCC) structure maximal compressive of 1140 MPa Vickers microhardness 654 HV room temperature. displays strong resistance to high‐temperature softening, showing the 244 °C. deformation compressed maybe resulted...
Abstract Material genetic engineering can significantly accelerate the development of new materials. As an important topic in material science and condensed matter physics, metallic glasses (MGs) with specific properties has largely been result trial error since their discovery 1960. Yet, property design based on physical parameters constituent elements MGs remains a huge challenge owing to lack understanding inheritance from constitute resultant alloys. In this work, we report inherent...
