Piling-ups of geometrically necessary dislocation (GND) arrays against interfaces are known to produce hetero-deformation induced (HDI) strengthening and strain hardening enhance the strength ductility heterostructured materials. Here we report an interesting mechanism that can strong HDI hardening: consecutive reflections GND planar piling-up near opposite phase boundaries in a AlCoCrFeNi2 high entropy alloy (HEA). In contrast, transmission was found at grain fcc phase. The discovery here...
BiSbTe has been realized as an ideal p-type thermoelectric material near room temperature; however, its commercial applications are largely restricted by n-type counterpart that exhibits relatively inferior performance.
Ultrastrong materials can notably help with improving the energy efficiency of transportation vehicles by reducing their weight. Grain refinement severe plastic deformation is, so far, most effective approach to produce bulk strong nanostructured metals, but its scaling up for industrial production has been a challenge. Here, we report an ultrastrong (2.15 GPa) low-carbon nanosteel processed heterostructure and interstitial mediated warm rolling. The consists thin (~17.8 nm) lamellae, which...
The binary compound of GeTe emerging as a potential medium-temperature thermoelectric material has drawn great deal attention. Here, we achieve ultralow lattice thermal conductivity and high performance in In heavy content Cu codoped thermoelectrics. dopants improve the density state near surface Femi by introducing resonant levels, producing sharp increase Seebeck coefficient. codoping not only optimizes carrier concentration but also substantially increases mobility to value 87 cm2 V-1 s-1...
The cold metal transfer (CMT) process, one of wire and arc additive manufacturing, was utilized to fabricate 316L stainless steel. As-built CMT consists austenitic coarse columnar grains aligned with depositing direction mainly tiny areas scattered ferrite (less than 5%) in dendrite. For comparison purposes, both as-built annealed wrought were dynamically characterized by Split-Hopkinson Pressure Bar. owns a nearly isotropic characteristic dynamic compressions. Compared material, yield...
