Segregation stabilizes nanocrystalline bulk steel with near theoretical strength.
Grain refinement through severe plastic deformation enables synthesis of ultrahigh-strength nanostructured materials. Two challenges exist in that context: First, deformation-driven grain refinementExpand

IDENTIFICATION OF YEASTS ISOLATED FROM HIGH-SUGAR FOODS
Yeast strains were isolated from 265 samples of high-sugar foods and related materials, and 93 representative strains were identified. Fifty-four strains of ascosporogenous yeasts were identified asExpand

Atomic-scale mechanisms of deformation-induced cementite decomposition in pearlite
Pearlitic steel can exhibit tensile strengths higher than 5 GPa after severe plastic deformation, where the deformation promotes a refinement of the lamellar structure and cementite decomposition.Expand

Evolution of strength and microstructure during annealing of heavily cold-drawn 6.3 GPa hypereutecto
Hypereutectoid steel wires with 6.35 GPa tensile strength after a cold-drawing true strain of 6.02 were annealed between 300 and 723 K. The ultrahigh strength remained upon annealing for 30 min up toExpand

Multiscale characterization of White Etching Cracks (WEC) in a 100Cr6 bearing from a thrust bearing test rig
Abstract A common cause for premature bearing failures in wind turbine gearboxes are the so-called White Etching Cracks (WEC). These undirected, three-dimensional cracks are bordered by regions ofExpand

Formation of nanosized grain structure in martensitic 100Cr6 bearing steels upon rolling contact loading studied by atom probe tomography
To understand the origin of white etching cracks (WECs), a systematic microstructural characterisation in the regions affected from the near-surface region down to the subsurface layers where WECsExpand
