High strength nickel based alloys are used in a multitude of advanced systems where lightweight, high power density mechanical power transmission systems are required. Components such as gears, bearings and shafts could be made significantly smaller and more durable if a major improvement in nickel based alloy mechanical properties could be achieved ...

Direct Observation of Matrix‐to‐Precipitate Elemental Diffusion in Severe Plastic Deformation
ABSTRACT Elemental redistribution, particularly the solute exchange between the matrix and precipitates, is a central issue in alloys subjected to severe plastic deformation (SPD). To elucidate this behavior, a nickel–aluminum bronze (NAB) alloy was processed by high‐pressure torsion (HPT), and its microstructural evolution was systematically ...

We introduce a versatile 3D platform that recreates key physical and biological features of the human bone marrow. By integrating tunable silk biomaterials, stromal cells, and human hematopoietic progenitors, the model captures both healthy and diseased microenvironments, analysis of blood formation, and its disruption in pathological conditions ...

Development of SPD continuous processes for strip and rod production
Grain refinement upon the severe plastic deformation (SPD) at low temperatures (below the recrystallization temperature) and an unusual improvement the properties of such materials are shown reliably. However, the industrial application is limited due to
