Abstract

IN the May lecture to the Institute of Metals, Dr. Korber, of Dusseldorf, describes his investigations into the plastic deformation of metals. These are well known to many from the original German publications, but the convenient and well illustrated summary here given will be of much value to metallurgists, being rich in suggestions bearing on the general problem of deformation. As has frequently been the case in recent years, the light alloys form the subject of a number of communications-, perhaps the most striking of which is the description of the protection of magnesium and some of its alloys by the deposition of a film of selenium. The film is self-healing to a certain extent, and serves as a basis for paint or enamels, which it causes to adhere firmly. The ‘fogging’ of nickel is shown to be due to the action of sulphur compounds hi the presence of moisture, a basic sulphate being the final product. It is largely inhibited by a preliminary formation of a thin film of sulphide.
