Synthetic-Hydroxyapatite-Based Coatings on the Ultrafine-Grained Titanium and Zirconium Surface
The development of biocompatible materials is a multidisciplinary task and requires the interaction of physicists, chemists, biologists, and physicians, since the functional reliability of materials depends on their biochemical, cellular, tissue, and ...

Crystal plasticity simulation of macroscopic yielding behavior of ultrafine-grained aluminum
High-strength, light-weight metal materials are required to improve safety and reduce transportation cost. Ultrafine-grained metals produced by severe plastic deformation have attracted interest as high-strength materials.

Additional grain boundary strengthening in length-scale architectured copper with ultrafine and coarse domains [PDF]
The strength of polycrystals is known to increase with decreasing grain size, known as Hall-Petch effect. However, this relationship fails to predict the strength of samples with a non-uniform distribution of grain sizes.

Grain growth in ultrafine-grained Y-TZP ceramics [PDF]
Grain growth in dense ultrafine-grained (120–600 nm) tetragonal ZrO2-Y2O3 ceramics is studied as a function of temperature. At all temperatures investigated both segregation and phase partitioning occur.

Thermal stability of the microstructure of severely deformed copper [PDF]
Copper specimens were deformed by equal channel angular pressing (ECAP) up to 8 passes. The microstructure was studied by X-ray line profile analysis. The crystallite size is reduced to a few tens of nanometers even after the first ECAP pass and it does ...

The mechanical behaviour of an ultrafine grained Ti-47Al-2Cr (at%) alloy in tension and compression and at different temperatures [PDF]
A bulk ultrafine grained (UFG) Ti-47Al-2Cr (at%) alloy has been produced using a powder metallurgy process that combines high energy mechanical milling (HEMM) of a mixture of Ti, Al and Cr powders to produce a Ti/Al/Cr composite powder and hot isostatic ...

Potential of ultrafine grained materials as high performance penetrator materials
The shear formability and the metal jet formability are important for the kinetic energy penetrator and the chemical energy penetrator, respectively. The shear formability of ultrafine grained (UFG) steel was examined, mainly focusing on the effects of ...
