Formation of glassy Ti50Cu20Ni24Si4B2 alloy by high-energy ball milling
The elemental powder mixtures with a nominal composition of Ti50Cu20Ni24Si4B2 can be amorphized under high-energy ball milling. A well-defined glass transition before crystallization appears in the obtained amorphous phase during heating in a differential scanning calorimeter. Awide supercooled liquid region DTx is available to be about 57 K. Crystallization of the ballmilled amorphous phase wa...
متن کاملReview of Micro-Particles of Hydroxyapatite Nanoparticles by Ball Milling

The aim of this study was to construct nano-hydroxyapatite micro particles using calcite, silica and zinc oxide using ball milling, powder, thes...
متن کاملMechanochemical decomposition of pentachlorophenol by ball milling.
The mechanochemical dechlorination of pentachlorophenol (PCP) was studied using CaO and SiO2 powder as additives. The effects of the milling time and additives on the dechlorination rate were investigated. The resulting product was characterized by X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TG) and ion chromatography (IC). It is found that g...
متن کاملEffect of CaO on the Formation of PSZ and γ-Zirconia Nanoparticles through Ball Milling
The effect of CaO on the formation of β- and γ-zirconia nanoparticles from α-zirconia was investigated and their stability evaluated via mechanical activation. α-ZrO2+8.5wt%CaO powder was milled for 2-150 hours with ball-to-powder weight ratios (BPWR) of 40:1 and 60:1. Structural evaluations were conducted using X-Ray diffraction and scanning electron microscope (SEM). Thermal analysis wa...
