Abstract

1382026 Eutectic alloys DEFENCE SECRETARY OF STATE FOR 15 Feb 1972 [17 Nov 1970] 54584/70 Heading C7A A composite is composed of (i) an aluminide of Ni or Co and (ii) a compound of Mo with Cr or Si, the two compounds being present in proportions to give an eutectic composition. The composite, which may be used for gas turbine blades, is preferably made by unidirectional solidification.
