Bodycote, Macclesfield, England, announces that it has acquired Nitrex Metal Technologies, which specializes in precision gas nitriding and ferritic nitrocarburizing in both batch and continuous processes.
Because of the use of nitrogen as an alloying element in these stainless steels, chromium nitrides (CrN) may be present on α/α grain boundaries, on γ/α boundaries, and within the α grains. If formed in large quantities and under conditions in which the chromium-depleted areas do not have time to repair themselves during annealing, the presence of CrN may adversely affect corrosion resistance.
Uranium mining methods produce a liquid with uranium dissolved in it. This is filtered and the uranium is then separated by ion exchange, precipitated from the solution, filtered, and dried to produce a bright yellow uranium oxide concentrate known as ‘yellowcake,’ which contains 0.7% U235.
The University of Toronto announces that Distinguished Professor in Plasma Engineering Javad Mostaghimi has been elected a Fellow of the Royal Society of Canada for his research on simulating the dynamics of droplet impact and solidification in thermal spray coating processes.
To celebrate the 50th anniversary of the original Star Trek series premiere, physics professor (and sci-fi fan) David Grier offers a look into his New York University lab—the birthplace of the real-life tractor beam.
