The crystalline structures of the superionic high-temperature copper selenides Cu(2-x)Se (0 < x < 0.25) produced using mechanical alloying were investigated using X-ray diffraction (XRD). The measured XRD patterns showed the presence of peaks corresponding to the crystalline superionic high-temperature alpha-Cu(2)Se phase in the as-milled sample, and its structural data were determined by means...

The present study was carried out to investigate the effect of alloying elements and thermo-mechanical treatment (TMT) i.e. hot rolling and forging with different reduction ratios on the hardness (HV) and impact toughness (J) of heat-treated low alloy steels. An understanding of the combined effect of TMT and alloying elements and by measuring hardness, impact toughness, resulting from differen...

Metal matrix composites are the class of composite materials finding vast applications in automotive, aircraft, defense, sports and appliance industries. A horizontal ball mill has been fabricated for milling of aluminum and SiC particles. The change in powder particle morphology during mechanical alloying of Aluminum and SiC powders using horizontal ball mill was studied. Al-SiCp composites wi...

Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing co...

In this work TiNi-based nanocrystalline alloys and composite were produced by mechanical alloying process with subsequent annealing at 750 ◦C for 0.5 h. Mechanical alloying was performed in a SPEX 8000 Mixer Mill. TiNi alloy was chemically modi ed by Ag elemental powder. Silver content equaled 5 wt%. X-ray di raction analyses revealed formation of TiNi main phase after annealing. Additionally, ...

As bioabsorbable materials, magnesium alloys are expected to be totally degraded in the body and their biocorrosion products not deleterious to the surrounding tissues. It's critical that the alloying elements are carefully selected in consideration of their cytotoxicity and hemocompatibility. In the present study, nine alloying elements Al, Ag, In, Mn, Si, Sn, Y, Zn and Zr were added into magn...
