Ballend milling was performed on a Precitech Freeform 3000 multiaxis ultraprecision machine using a carbide tool for premachining and a halfarc diamond tool with a nose radius of 3 mm for finishing.
Ball milling was employed to produce Zr 65 Ag 5 Cu Ni 10 Al glassy powder from prealloyed mixtures of crystalline intermetallic compounds. Differential scanning calorimetry (DSC) in isochronal as well as in isothermal modes was used to study the thermal stability and the crystallization kinetics of .

After mixing by ball milling, the Al 2 O 3 nanoparticles were found embedded into the surface of SnAgCu solder powder. Moreover, microstructure observation proved Al 2 O 3 nanoparticles were successfully incorporated into the SAC solder.
Among metals, tungsten have the highest melting points, it is a significant refractory metal and keep good high temperature strength; heavy tungsten alloy bears high density, very high melting points, excellent creep resistance, heat conductivity, as well as electronic emission .tungsten alloys is an optimal counterweight material, alloy ...
The Ravenswood Mining Landscape and Chinese Settlement Area, a distinctive, heavily modified landscape punctuated by brick chimneys, mullock heaps and other remnant mining structures, is an evocative reminder of the precarious and shortlived nature of Queensland's mining booms.
