Microstructure evolution and catalytic activity of AlCoFeNiTiMo high entropy alloys fabricated by powder metallurgy route.

This investigation presents the synthesis of equiatomic and non-equiatomic AlCoFeNiTiMo (x = 0, 0.1, 0.25 and 1.

Effect of different fillers on thermal conductivity, tribological properties of Polyamide 6.

An influence of different filler types and filler content on the thermal and abrasive wear properties of polyamide-6 is investigated. AlO, MgO, two glass powders with different SiO contents, and natural zeolite powder were selected as fillers. The fillers individually were added to the polymer matrix in proportions of 50 and 70% by weight.

Influence of the Oxide and Ethanol Surface Layer on Phase Transformation of Al-Based Nanocomposite Powders under High-Energy Milling.

Pure Al particles reinforced with amorphous-nanocrystalline CuZrAgAl particles composite powders were prepared by high-energy milling without and with ethanol. The mechanical milling procedures were compared so that in the case of dry milling the particle size increased owing to cold welding, but the crystallite size decreased below 113 nm. The amorphous phase disappeared and was not developed until 30 h of milling time.

Phase Transformation and Morphology Evolution of TiCuNiSn₅ during Mechanical Milling.

Nanocrystalline/amorphous powder was produced by ball milling of TiCuNiSn₅ (at.%) master alloy. Both laser diffraction particle size analyzer and scanning electron microscope (SEM) were used to monitor the changes in the particle size as well as in the shape of particles as a function of milling time.
