Spinodal decomposition is discovered to be an effective way strengthen magnesium alloy.
Body-centred cubic magnesium-lithium-aluminium-base alloys are the lightest of all structural alloys, with recently developed alloy compositions showing a unique multi-dimensional property profile. By hitherto unrecognised mechanisms, such also exhibit exceptional immediate strengthening after solution treatment and water quenching, but strength eventually decreases during prolonged low temperature ageing. We show that phenomena due to precipitation semi-coherent D03-Mg3Al nanoparticles...
The microstructural features of a high-strength body-centered cubic Mg-Li–Al-Ag alloy are investigated and the strengthening mechanisms discussed. results show that obvious spinodal decomposition occurs in alloy. Owing to diffusion Al atoms Ag-vacancy pairs, co-clustering Ag is observed. compositional redistribution Li matrix reduces interfacial lattice misfit thus lowers strain energy. Combinatorial with coherency hardening result high strength achieved dual alloying strategy opens avenues...
The low hardness and poor wear resistance of laser-cladding 316L stainless steel impose significant constraints on its practical applications. In this study, a strategy for strengthening with WMoTaNb refractory high-entropy alloy as reinforcement material is proposed. results confirm that the coating primarily comprises body-centered cubic (BCC) Fe-based solid solution, network-distributed hexagonal Fe2X (X = W, Mo, Ta, Nb) Laves phase, diffusely distributed face-centered (FCC) (Ta, Nb)C...
Underwater optical communication and low-light detection are usually realized via blue-green laser sources light-sensitive detectors. Negative-electron-affinity AlGaAs photocathode is an ideal photosensitive material for ocean exploration due to its adjustable spectrum range, long working lifetime, easy epitaxy of materials. However, compared with other photocathodes, the main problem low quantum efficiency. Based on Spicer’s three-step photoemission model, nanoarray structures designed...
Twins are generally regarded as obstacles to dislocations in face-centered cubic metals and can modify individual by locking them twin boundaries or obliging dissociate. Through situ tensile experiments on Al thin film a transmission electron microscope, we report dynamic process of being transported lamella via periodic twinning detwinning at the atomic scale. Following this process, 60° dislocation first transforms into sessile step boundary, then migrates under stress finally reverts back...
