(3) Nontoxic and harmless reactants to human health and the environment and simple precursors should be used in synthesis techniques whenever applicable and practical. (4) The synthesis routes should preserve the targeted properties of the products. (5) Synthesis techniques employing low energy ...
qt=kit1/2+C (9) where,kiis the intraparticle diffusion rate constant. The value ofCgives prediction about the boundary layer thickness. If intraparticle diffusion occurs,qtvs.t0.5is linear and if the plot cross through the origin, the rate determination is only due to the intraparticle diff...

Date Jul. 26, 1990.Device and method for feeding molten metal for the pressure casting of metal products. The device for feeding molten metal to a mould 1 of a continuous pressure-casting installation comprises a vessel 2 equipped with a cover 7 carrying a spout 3, the said vessel resting...
Also, the alloy was well processable in casting, forming, and welding [34]. A study on the effect of adding Sc to hypoeutectic and hypereutectic Al alloys found that a refinement effect is induced on the latter rather than the first. With the cooling of the ingots, Sc is supersaturated ...
as a plurality of struts of which an upper strut (20) is interleaved between the blocks (31); the extremities (20b) of the upper strut (20) and of the front strut are interleaved between two half-chills (41, 42) which receive a dead-head of liquid metal at the end of the casting...
