We propose a method using high-velocity ballistic impacts of deformable microparticles on a rigid target to assess particle strength at strain rates exceeding 10 6 /s. High-speed imaging allows us to view particle behavior in-situ, which is then compared to models to elicit insight into plasticity. Over a range of velocities, the power-law decline of the rebound Dynamic recrystallization helps to refine grain structures in metals and tune their properties.

Severe plastic deformation (PD), especially involving high strain rates (>103 s–1), occurs through solid-state flow, which is accommodated by dynamic recrystallization (DRX), either in a continuous or discontinuous mode. This flow can be localized in shear instability zones (or adiabatic shear bands (ASBs)) with dimensions smaller than 5 μ, or can include large volumes Cross-Twin driven dynamic recrystallization regulates grain orientation: High-density {10−12} cross twins serve as preferential nucleation sites for DRX during shear deformation. 亲爱的研友该休息了！由于当前在线用户较少，发布求助请尽量完整的填写文献信息，科研通机器人24小时在线，伴您度过漫漫科研夜！身体可是革命的本钱，早点休息，好梦！ 已完结 标题 Nanotwinning-assisted dynamic recrystallization at high strains and strain rates 相关领域 再结晶（地质） 材料科学 纳米晶材料

The new pathway, which they call nano-twinning assisted recrystallization, is a variation of a known phenomenon in metals called twinning, a particular kind of defect in which part of the crystalline structure flips its orientation. Dynamic recrystallization helps to refine grain structures in metals and tune their properties. Confining recrystallization within prior nanoscale twinning provides a path for reaching exceptional grain refinement.

Nanotwinning-assisted dynamic recrystallization is shown to facilitate grain refinement to the nanoscale at high strains and strain rates.

Dynamic recrystallization helps to refine grain structures in metals and tune their properties. Confining recrystallization within prior nanoscale twinning provides a path for reaching exceptional grain refinement. Above 1350 K, the softening caused by dynamic recovery and dynamic recrystallization becomes more pronounced, surpassing the influence of work hardening on high-temperature deformation. Continuous dynamic recrystallization is identified as the primary mechanism driving the dynamic recrystallization.

The theoretical strength of a material is the minimum stress to deform or fracture the perfect single crystal material that has no defects. This theoretical strength is considered as an upper bound on the attainable strength for a real crystal. In contradiction to this expectation, we use quantum mechanics (QM) simulations to show that for the boron carbide (B4C) hard ceramic, this 标题 Nanotwinning-assisted dynamic recrystallization at high strains and strain rates 高应变和应变速率下纳米孪晶辅助的动态再结晶 相关领域 再结晶（地质） 材料科学 纳米晶材料 动态再结晶 电子背散射衍射 粒度 应变率 冶金 纳米技术 微观结构 热加工 地质学 古生物 Recrystallization phenomena induced by such treatments may lead to average crystal sizes as low as hundreds of nanometres. Now, writing in Nature Materials, Ahmed Tiamiyu and colleagues 4 report a recrystallization mechanism leading to crystal sizes of tens of nanometres.

Moreover, in the stress relaxation experiments re/erred to above, fluid-assisted recrystallization was found to be influenced by confining pressure, being inhibited at pressureslow enough to permit dilatation. This effect of pressurecould significantly influence theology under conditionsfavoring dislocationcreep.

Older research outputs will score higher simply because they’ve had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 427,859 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 58% of its contemporaries . Grain refinement is a widely sought-after feature of many metal production processes and frequently involves a process of recrystallization. Some processing methods use very high strain rates and high strains to refine the grain structure into the nanocrystalline regime.
