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 کاملDestabilized LiBH4/MgH2 for reversible hydrogen storage
DOE and FreedomCAR technical targets of 6.0 and 9.0 wt.% are set forth capacities to realize a “holy grail” for hydrogen storage systems for 2010 and 2015 respectively. Alkali metal complex hydrides with high theoretical hydrogen capacity, for example: LiBH4 (18 wt.%), are being investigated for their properties to store large quantities of hydrogen. The catalytic doping of SiO2, seems to enhan...

متن کاملQuenching ilmenite with a high-temperature and high-pressure phase using super-high-energy ball milling
The mass production of highly dense oxides with high-temperature and high-pressure phases allows us to discover functional properties that have never been developed. To date, the quenching of highly dense materials at the gramme-level at ambient atmosphere has never been achieved. Here, we provide evidence of the formation of orthorhombic Fe2TiO4 from trigonal FeTiO3 as a result of the high-tem...
متن کاملMechanical Synthesis of Iron and Nickel Solid Solution by High Energy Ball Milling for Packaging
Mechanical alloying (MA) is a solid-state powder processing technique involving repeated cold welding and fracturing of powder particles in a high-energy ball mill. It has been used to obtain nanocrystalline binary system FeNi. Fe and Ni elemental powders have been ball milled in a planetary mill (Pulverisette5, Fritsch) for various times up to several hours. The morphology of the powders was e...
