(1) Aluminium and its Alloys (2) The Institution of Mechanical Engineers: Eleventh Report to the Alloys Research Committee: on Some Alloys of Aluminium (Light Alloys)

Abstract

(1) LIEUT.—COL. GRARD'S book is essentially a treatise on the mechanical properties of aluminium and some of its commercial alloys. The extraction of the metal is described in two pages, and no more detail is given than in an elementary textbook, although there are several plates showing the power houses of Continental works. The account of the economic position of the industry is also too meagre to be of much use. The valuable part of the book consists of a long series of diagrams of mechanical properties of metal that has been subjected to various thermal and mechanical treatments, and of a corresponding series for certain of the light alloys and for the aluminium bronzes. Tensile strengths are given in metric and British units-an excellent practice.
