A review of mechanical alloying processes has been published by Froes et al. (1995). 

Milling atmosphere, which is a neutral protective gas (helium or argon) during mechanical milling or hydrogen under pressure up to 0.9 MPa under reactive mechanical alloying processes. 

For Ag(lOO) crystals, a similar electrochemical behavior was observed with quasi-reversible adsorption/desorption of Cd and surface alloying, faster than for Ag(lll) [286]. Electrochemical and AFM experiments have shown that the alloying process consisted of two steps a very fast reaction occurring within a few atomic layers, and a much slower one, represented by a solid-state diffusion process [244]. 

Vidu et al. [424] have studied the kinetics of thin alloy film formation and growth during Cd electrodeposition on Au(lOO) and Ag(lOO) within the Cd UPD range from —0.3 to —0.45 V. Electrochemical and AFM experiments in 1 mM CdS04 and 0.05 M H2SO4 solutions have revealed that the overall alloying process comprises two processes the first occurring relatively fast within a few atomic layers (D 10 , and the second much slower... 

Aluminum cladding is an alloying process used to help prevent surface corrosion of other underlying metal components. This process involves hot rolling metal to produce a protective aluminum barrier. Clad aluminum alloys can be found in some heat exchanger tubing applications.

The manufacture of tetraethyllead presented many problems historically because there was no prior experience in the large-scale production of any organometallic compounds. There have been innumerable patents issued to protect various modifications of the basic process. The original major contribution to the development of a commercially successful alloy process for tetraethyllead was the demonstration by Kraus and Callis 194,193) 0f the conditions required for the facile reaction of the sodium-lead alloy with ethyl chloride. The development of the process has been reviewed by several writers 120,121,277,289,290,310,315), Additional important early patents on the process are those of Calcott and Daudt 64,103).
