THE remarkable changes in properties which may be achieved by the addition of small quantities, or traces, of certain elements to age-hardening alloy systems has aroused much interest recently. A notable example is the pronounced effect of traces of cadmium, indium, or tin on the elevated temperature ageing characteristics of aluminium-copper alloys1. Similar observations have been made in a number of alloys; but, with the exception of a study of trace element additions to ternary aluminium-copper-lithium alloys2, investigations have been confined to binary systems.
