Abstract
THIS volume is the last of the present series. In future, the papers read before the Institute of Metals will appear, as before, in half-yearly volumes, but the abstracts will form a third volume, published annually. The papers read at the Southampton meeting include several on aluminium alloys, including an illuminating discussion of the methods of refining the grain size of aluminium by the use of volatile chlorides or of chlorine-bearing vapours. It appears that the entry of water vapour from products of combustion into aluminium and its alloys may be particularly harmful. An interesting monograph on the origin and development of rolled gold contains information which will be new to most readers, on a material in familiar use. Further work has been done on the atmospheric corrosion of copper, and a basic sulphate is shown to be the principal constituent of the product in ordinary atmospheres, largely replaced by the basic chloride in marine situations. Prof. Tammann has contributed a paper on the determination of crystallite orientation in metals, which will be found useful as a summary of numerous papers by that author which have appeared elsewhere. The plates are, as usual, excellently produced.
