Mechanical alloying of AlTi alloys
Materials Science and Engineering: A, 1990Abstract Mechanical alloying has been used to mix elemental powders of aluminium and titanium and to produce mixtures of aluminium and Al 3 Ti phases during heat treatments for consolidation. Alloy concentrations of 12.5–26 at.% Ti have been covered, corresponding to alloys containing 50–100 at.% Al 3 Ti after reaction.

Microstructure of mechanically alloyed Al-In alloys [PDF]
Journal of Materials Science, 1994 Mechanical alloying (MA) starting from elemental powder mixtures was performed on immiscible Al-10, 30 and 50 at % In alloys. Al and In were finely mixed with increasing MA time and the crystal size of each element became up to 40 nm after MA for 1152 ks.

Publisher Summary An alloy is a substance that has metallic properties and is composed of two or more chemical elements, of which the primary one is a metal. Homogeneous alloys consist of a single phase and mixtures consist of several phases. There are three possible phases in the solid state: pure metal, intermediate alloy phase or compound, and ...

Laser Alloying of Copper and its Alloys [PDF]
, 1996 Laser surface alloying of copper, yellow brass and Al Bronze were carried out by duplex process involving powder alloying followed by remelting using an inclined plasma jet spraying nozzle. The aim of this investigation was to study the rapidly solidified non-equilibrium phases of copper alloys and their properties. The copper and brass substrates were

Mechanical alloying – the development of strong alloys
Materials Science and Technology, 1986AbstractMechanical alloying is a solid-state process for making alloys by high-energy milling, under conditions such that constituent powders are repeatedly fractured and welded together and ever more intimately mixed. After subsequent consolidation at elevated temperature, the alloys can be shaped by rolling, forging, and machining.

Laser alloying of aluminium alloys with chromium
Surface and Coatings Technology, 1995Abstract The microstructure and corrosion resistance of laser-alloyed aluminium and ANSI 7175 aluminium alloy with chromium were investigated. Surface layers alloyed with chromium contain relatively large amounts of intermetallic compounds dispersed in a matrix of α-Al.

A Study in Surface Alloying of Titanium Alloys
Journal of Laser Applications, 1989A 5 KW CW CO2 laser has been used to alloy the surface of Ti6Al4V alloy with carbon. As a result the average microhardness was increased from 365 to 600 kg/mm.2 Compositional inhomogeneity was observed on the alloyed surface, however the compositional inhomogeneity index reduced considerably by cross scanning with defocused laser beam.

Production of CoNi alloys by mechanical-alloying
Journal of Alloys and Compounds, 1996Abstract Co Ni solid solutions, such as Co10Ni20, Co40Ni40, Co50Ni50, Co60Ni40 and Co70Ni30 alloys, have been produced by mechanical-alloying using Co and Ni powders prepared in our laboratory by the polyol process as metallic precursors. The grinding transforms the hexagonal Co phase into a cubic Co phase by stacking fault creation and permits a ...
