Abstract Superplastic metals that exhibit exceptional ductility (>300%) are appealing for use in high‐quality engineering components with complex shapes. However, the wide application of most superplastic alloys has been constrained due to their poor strength, relatively long deformation period, and high‐cost grain refinement processes. Here these issues addressed by coarse‐grained superplasticity high‐strength lightweight medium entropy alloy (Ti 43.3 V 28 Zr 14 Nb Mo 0.7 , at.%) a...
The high-entropy alloy coatings reinforced with nano oxides were synthesized by the atmospheric plasma spraying (APS). crystal structure, microstructure, surface morphology, hardness and wear resistance properties of CoCrFeNiAl CoCrFeNiMo are investigated. For high entropy coating (HEC) not only has (573 ± 19 Hv0.1) but also good [The coefficients friction (COF) is 0.49 0.04]. transition mechanism obviously appears between two HECs. influences composition on tribological behavior discussed...
High-entropy alloy coatings (HEAC) exhibit good frictional wear and corrosion resistances, which are of importance for structure materials. In this study, the microstructure, surface morphology, hardness, resistance an AlCoCrFeNi high-entropy coating synthesized by atmospheric plasma spraying (APS) were investigated. The simultaneously improved with increase power APS. influence APS process on microstructure mechanical behavior is elucidated. mechanisms HEAC discussed in detail.
The low-density refractory medium entropy alloys (NbTiVZr, Nb0.5TiVZr and NbTiV) were produced by vacuum arc melting then heat-treated at 1200 ℃ for 1 h, following water quenching finally annealed 500 0.5 h. microstructures, elevated temperature mechanical properties thermal expansion behavior investigated correspondingly. All the are characterized BCC structure with grain size around 85 ~ 135 m. Results demonstrated that NbTiVZr alloy exhibits relative high yield strength specific...
A TiAl 3 -rich coating was developed by hot-dip aluminizing method and subsequent interdiffusion treatment on Ti-6.5Al-1Mo-1V-2Zr (mass %) alloy for high temperature resistance.Interrupted oxidation at temperatures from 973 to 1173 K isothermal 923 1073 of the were conducted.The markedly decreased rate in comparison with substrate lower during interrupted oxidation, a layered structure Al 2 O /TiAl /TiAl/alloy outside inside formed after without changing main body coating.The kinetics...

Built the RFID (Radio Frequency Identification) hardware system then developed a tool management based on Labview in paper. The software can control read/write device to data through serial port and use database module add, query, modify delete record. So, automatic identification of cutting is realized.
The correlation between the intergranular corrosion (IGC) behavior and aging tem- per (including T6 at 150 175 ℃, T8 ℃) of 2099 Al-Li alloy was investigat- ed. Then a diagram established to describe relation IGC with procedure. Ac- cording resulted morphology alloy, process might be divided into four stages: i.e. stage I is initial stage, II under-aging III near-optimal IV over-aging stage. aged showed different modes after by pitting or local (LIGC) for I; general (GIGC) II; LIGC III; pit-...
Considerable effort has been applied toward developing refractory high-entropy alloys (RHEAs) with both high strength and good ductility. However, the deformation fatigue failure mechanisms of these under cyclic loading remain poorly understood . The present work addresses this issue by investigating low-cycle behavior microstructural evolution an HfNbTiZr RHEA a nominal composition 25 mol% each Hf, Nb, Ti, Zr forming balance symmetric tension-compression conditions at room temperature....
