Substitute Alloys

IN the wake of depleting mineral reserves and their shortages and in certain cases, in the almost total absence of some, researches and applied technological efforts are continuously directed towards mineral cons-ervation on the one hand and making the maximum optimum
use of available resources on the other. In doing so, unconventional uses have to be made of different metals and their alloys through the judicious development
'substitute' ferrous and non-ferrous families of alloy compositions. The subject of substitute alloys has
always tended to be somewhat controversial adjudged
on the basis of indigenous availability of the primary metals not only in relation to metallurgical acceptabi-lity of the substitute alloys but also vis-a-vis their production economics, consumer acceptance and service-ability.
