Chaudhuri, B and Das, P P (1968) Effect of different variables on the precipitate-free zones adjacent to grain boundary regions on convention- ally quenched and aged Ai-Zn-Mg alloys. In: UNSPECIFIED.
THE Eleventh Report to the Alloys Research Committee of the Institution of Mechanical Engineers prepared by Rosenhain, Archbutt and Hanson1 in 1921, recorded a tensile stress exceeding 40 tons,/in2 in a wrought alu-minium alloy containing 20% zinc along with magnesium, copper and manganese but did not recommend this type of alloy for use on account of season cracking. Recognition of the outstanding mechanical properties of Al-Zn-Mg alloys at lower ranges of zinc content was due to work carried out by Sander and Meissner2 in 1926, which also indicated the significance of corrosion as a factor in cracking under prolonged stressing i.e., stress-corrosion cracking. lnspite of intensive studies over the past 40 years leading to wide adoption by the aircraft industry of alloys of this basic type, relationships between composition, stress level and cracking in service are still undefined.
