Here we report an “intragranular ultra-nano precipitation” strategy to strongly plasticizing
and simultaneously strengthen polycrystalline Cu alloys. Our strategy relies on a high …

A trend of strengthening accompanied by a loss of ductility is generally true for metals and
alloys processed in various methods for hundreds years. In the future, increasing the …

Grain refinement to the nano/ultrafine-grained regime can make metals several times
stronger, but this process is usually accompanied by a dramatic loss of ductility. Such …

In this paper, the research progress on the strengthening of copper and copper alloy is
reviewed. The research shows that traditional strengthening methods are often …

Both strengthening effects of gradient nanostructure (especially the gradient nanotwins) and
nanoprecipitates have been well-recognized to simultaneously improve the mechanical …

Nanograined metals have the merit of high strength, but usually suffer from low work
hardening capacity and poor thermal stability, causing premature failure and limiting their …

Ultrafine-grained materials produced by different severe plastic deformation methods show
very high strengths but their tensile ductility is often very low. In the present work, we …

We fabricated ultrafine-grained (UFG) Cu–Cr–Zr alloy including fine second-phase particles
via an accumulative roll-bonding process and subsequent aging treatment. The nanosized …

Bulk ultrafine grained (UFG)/nanocrystal metals possess exceptional strength but normally
poor ductility and thermal stability, which hinder their practical applications especially in high …

A bulk nanostructured alloy with the nominal composition Cu–30Zn–0.8 Al wt.%(commercial
designation brass 260) was fabricated by cryomilling of brass powders and subsequent …
