Nov 16, 2016nbsp018332cu-cr-mo alloy could be a suitable candidate material for collector electrodes in high-power microwave tube devices.an attempt has been made to synthesize ternary cu-cr-mo alloys by mechanical alloying of elemental cu, cr, and mo powders, to extend the solid solubility of cr and mo in cu, using a commercial planetary ball mill.for the first ternary alloy, a mixture of 80 wt.% cu, 10.
The invention concerns a method for making an intermetallic alloy comprising iron and aluminium, reinforced by ceramic compound dispersoids, comprising the following steps preparing a pre-alloyed powder of a parent alloy of iron and aluminium dry grinding under neutral gas said pre-alloyed powder in a ball mill, a ceramic compound powder with initial particle-size distribution not more than.
Pure copper powders with different amounts of 1, 3 and 6 wt% of commercial pure zirconium powders were mixed and milled in a planetary ball mill for different milling times of 4, 12, 48 and 96 h.results showed that the lattice parameter of copper increased with increasing milling time.
Jul 21, 2016nbsp018332the metallic glassy alloy powders for antibacterial coating are mechanically alloyed mixtures of copper, titanium, and nickel nanoparticles.the nanoparticles are alloyed by ball-milling to form glassy, metallic powders.the alloy preferably has a coppertitaniumnickel atomic percentage ratio of about 502030, referred to herein as cu50ti20ni30.
Process atomizing (gas) first the coarse metarial or ingot is melted in the furnace to get liquid metal.then the liquid metal is turned into droplets.then we cool the liquid and collect the powder.then sieve the powder and separate.we then collect the elaborate powder and mix them.at last we package the fashioned powder.
Synthesis of nanomaterials by high energy ball milling w.cao.it is critical to establish a balance between the two processes in order to alloy successfully.planetary ball mill is a most frequently used system for mechanical alloying since only a very small amount of powder is required..at the initial stage of ball milling, the powder.
