Nanostructured TiN/TiB2/Fe–Cr–Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form uniform mixture of TiN and TiB2 within 2 h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN nd TiB2 are about 7 and 16 nm, respectively, after 32 h of milling. Through liquid phase sintering and optimizing the ...

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...

This paper contains data and supporting information of and complementary to the research article entitled "Effect of jar shape on high-energy planetary ball milling efficiency: simulations and experiments" (Broseghini et al.,) [1]. Calcium fluoride (CaF2) was ground using two jars of different shape (cylindrical and half-moon) installed on a planetary ball-mill, exploring different operating co...

This study showed pronounced changes in the Raman scattering of silicon powder during high-energy ball milling. The powders were milled for 1–18 h in a steel ball mill in argon. The approximate pressure imposed on particles was 2 GPa. The spectra of the as-milled powders were compared with the initial silicon. It was found from the Raman peak position shifts that milling generated strains in th...

It is observed that large quantities of hydrogen (H2) are released at ambient temperatures during the mechano-chemical synthesis of the Li-Al-N-Mg-based hydride composites using an energetic ball milling in a unique magneto-mill. For the (nLiAlH4+LiNH2; n=1, 3, 11.5, 30) composite, at the molar ratio n=1, the LiNH2 constituent destabilizes LiAlH4 and enhances its decomposition to Li3AlH6, Al an...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...
