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.

Mechanical alloying of Fe-C alloys
International Journal of Microstructure and Materials Properties, 2007In this article, the effect of chemical composition and time of high-energy milling on the average diameter of particles and grains of powder of Fe-C alloy is discussed. The mechanical alloying processes of the Fe-0,4% mass.C and Fe-6,67% mass.C alloys were conducted.

On the Amorphisation of NiGe Alloys by Mechanical Alloying
1992We have studied the phase transformations induced in the Ni-Ge binary system by mechanical alloying of Ni and Ge powder mixtures and by milling of NiGe melt-spun ribbons. We observed that mechanical alloying is preceded by significant x-ray line broadening, consistent with an acceleration of the mixing kinetics with grain refinement.

Complex alloying and microalloying of titanium alloys
Welding International, 2011Theoretical and practical aspects of the titanium alloys complex, alloying and microalloying are considered. Complex alloying first principles are formulated. A series of complex-alloyed titanium alloys VT23, VT23L, VT23K, VT23m, VT43, etc. are developed.
