The Journal of the Institute of Metals

Abstract

THIS volume contains the papers which were read at the autumn meeting of the Institute of Metals in 1915, an account of which has already appeared in the columns of NATURE, together with the discussion and written communications. So far as these papers are concerned, the chief place in technical importance must certainly be given to that by Mr. Parker on specifications for alloys for high-speed superheated steam turbine bladding, which drew an important contribution from the president, Sir Henry Oram, the engineer-in-chief of the Navy. One of the special merits of this paper is that it makes a point of stating what are the chief requirements in modern specifications Of such alloys, and thus gives scientific workers definite problems of first-rate technical importance to work out. Prof. Edwards's paper on rttetallic crystal twinning by direct mechanical Strain is illustrated by some very fine photomicrographs, which will repay detailed study, and prove that, in the case of tin, at any rate, twins are formed by mechanical strain.
