Pressure is a critical component of preparation processes regardless its magnitude, whether it few megapascals, such as in metal squeeze casting, or thousands the experimental amorphous materials, quasicrystals and nanocrystals. Spinodal decomposition ordering are two common forms unstable phase transformation solid solutions. Reasonable regulation these transformations can effectively control microstructures improve properties. Therefore, study solution instability under effect ultrahigh...
Based on the excellent comprehensive mechanical properties of high–entropy alloy (HEA), NiAl-based HEA was designed to achieve high-temperature strength, toughness, and wear resistance. In this work, vacuum arc melting technology used prepare (NiA1)78(CoCrFe)16.5Cu5.5 HEA, its microstructure, phase composition, were systematically studied. The results showed that composed FCC BCC/B2, with a spinodal decomposition structure in matrix, nano-precipitation interdendritic, exhibiting good...
This study aims to comprehensively determine the influence of high pressure on microstructure and corrosion properties a designed high-entropy alloy (Al3Cr2Mo2SiTi2). By characterizing morphology alloy, we have confirmed that intermetallic compound volume fraction decreases peritectic reaction occurs during solidification process under 4 GPa. Moreover, phase A1 changes from (Ti, Mo)5Si3 (K1 phase) at ambient Mo)Si2 GPa, Cr-rich (C1 increases 20% 64%. special transformation, induced by...
