Guided by CALPHAD (Calculation of Phase Diagrams) modeling, the refractory medium-entropy alloy MoNbTaV was synthesized vacuum arc melting under a high-purity argon atmosphere. A body-centered cubic solid solution phase experimentally confirmed in as-cast ingot using X-ray diffraction and scanning electron microscopy. The measured lattice parameter (3.208 Å) obeys rule mixtures (ROM), but Vickers microhardness (4.95 GPa) yield strength (1.5 are about 4.5 4.6 times those estimated from ROM,...
Refractory high‐entropy alloys (RHEAs) with excellent high‐temperature performance are attractive for structural applications. However, many RHEAs suffer from high density and poor room temperature (RT) malleability. Herein, the effects of Ti Nb contents on phase equilibrium mechanical properties HfZrVTaMoWTi x y studied to achieve unique balanced in a wide range. With increase or content, Laves precipitation is suppressed RT malleability improved. Particularly, 2 RHEA without precipitates...
The refractory high-entropy alloys (RHEAs) have been the subject of considerable research in recent years. Since Laves phase usually leads to a dramatic decrease malleability RHEAs at ambient temperatures, it is critical identifying Laves-phase formation. Here, facile and effective criterion proposed predict stability based on empirical parameters reported RHEAs. results indicate that small atomic size difference sufficient condition for determining solid solution but not necessary one. In...
In this paper, PVDF hollow fiber membrane with high adsorption performance was prepared by coating polyvinyl alcohol on the surface of commercial ultrafiltration and initiating partial hydroxyl acetalization. The modification effect studied scanning electron microscopy, infrared spectroscopy, contact angle test organic dye capacity test. results show that is effectively fixed used as agent to initiate acetalization reaction in presence glutaraldehyde acid catalyst. pure water decreases from...

Fullerene (C60) was successfully grafted on cellulose following with the modification of by acid chlorination and subsequently azidation. The structures modified made sulfonation, acylating chlorination, Azidation, ionization fullerenated were determined infrared spectroscopy. results show that raw can obtain good dissolution property when methyl imidazole-chloropropylene ionic liquid is used as solvent system. choice intermediates has an important effect modification. better grafting...
