Grain refinement into the nanoscale greatly hardens metals and alloys but reduces the
stability. By means of cryogenic plastic deformation at very high strain rates, a high …

Ultrafine-grained and heterostructured materials are currently of high interest due to their
superior mechanical and functional properties. Severe plastic deformation (SPD) is one of …

Metal matrix composites (MMCs) incorporate a reinforcing or functional secondary phase
into a metal matrix to achieve specific properties. Of the parameters which may affect the …

A large fraction of grain boundaries imparts high strength to nanocrystalline (NC) metals but
causes the poor thermal stability of microstructures and a significant reduction of strength …

Pt and its alloys have important applications in the field of catalysis or in the jewellery
industry. Especially in the latter case sufficient strength is necessary to ensure wear …

In this article, the plastic strain mechanisms of AISI 316L with bimodal grain size distributions
are investigated using experimental characterizations and numerical simulations. Using …

Refractory high-entropy alloys have attracted widespread attention as potential structural
materials for high temperature applications. However, there is limited understanding of their …

Thermally activated deformation mechanisms in three different W-Re alloys were
investigated by performing high temperature nanoindentation experiments up to 800° C …

Due to the easy coarsening caused by poor thermal stability, the verified annealing-induced
hardening in nanograined metals can only maintain at a relatively low-temperature range. In …

The purpose of this study was to compare the influence of microstructural and textural
changes on the hardening by annealing effect in cold-rolled titanium. Ultrafine-grained …
