The Effect of Grain Direction on Mechanical Properties of Light Alloy Extrusions: A Report on a Series of Tests Carried Out by Vickers‐Armstrongs at Weybridge

Abstract

IT has been generally accepted for some time that the mechanical properties of light alloys varied with the direction of grain, but even in the design of aircraft structures only a slight allowance has been made for this variation. The importance of this grain direction on the strength of light alloys was first realized as a result of the abnormally low test strength of one lug made from a 6½″ dia. DTD.683 extruded bar.
