Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility

Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility.

Grain refinement can make conventional metals several times stronger, but this comes at dramatic loss of ductility. Here we report a heterogeneous lamella structure in Ti produced by asymmetric rolling and partial recrystallization that can produce an unprecedented property combination: as strong as ultrafine-grained metal and at the same time as ductile as conventional coarse-grained metal. It...

Nanodomained Nickel Unite Nanocrystal Strength with Coarse-Grain Ductility

Conventional metals are routinely hardened by grain refinement or by cold working with the expense of their ductility. Recent nanostructuring strategies have attempted to evade this strength versus ductility trade-off, but the paradox persists. It has never been possible to combine the strength reachable in nanocrystalline metals with the large uniform tensile elongation characteristic of coars...

Coarse Grain Reconfigurable Architectures

The paper gives a brief survey over a decade of R&D on coarse grain reconfigurable hardware and related compilation techniques and points out its significance to the emerging discipline of reconfigurable computing.
