Economies of scale at small integrated steelworks
Key features of alumina/magnesia/graphite refractories for steel ladle lining
The corrosion resistance of resin bonded alumina/magnesia/graphite refractories containing different kinds of aggregates were investigated when submitted to the action of slags of several CaO/SiO2 ratios. The laboratory ...
Sinterização de uma mistura de cavaco de aço inoxidável com pó do mesmo material. Uma nova tecnologia para a reciclagem de metais?
The reuse of materials has as its main objective to minimize environmental impacts and to rationalize the use of energy chains. In the present work, samples of scraps of 316 stainless steel mixed with powder of the same ...
Metallurgical evaluation of a copper-based alloy for dental castings.
The present study was designed to evaluate the metallurgical properties of an experimental, low-cost copper-zinc-aluminum-nickel alloy for dental castings. Some specimens were subjected to heat treatment after induction ...
Anodization mechanism on SiC nanoparticle reinforced al matrix composites produced by power metallurgy
(Mdpi Ag, 2014-12-01)
Specimens of aluminum-based composites reinforced by silicon carbide nanoparticles (Al/SiCnp) produced by powder metallurgy (PM) were anodized under voltage control in tartaric-sulfuric acid (TSA). In this work, the influence ...
Production of a low young modulus titanium alloy by powder metallurgy
(ABM, ABC, ABPol, 2005-12-01)
Titanium alloys have several advantages over ferrous and non-ferrous metallic materials, such as high strengthto-weight ratio and excellent corrosion resistance. A blended elemental titanium powder metallurgy process has ...
