(57) A rapidly quenched, cast metallic strip (30) is disclosed comprising a plurality
of dissimilar portions (a. b. c, d), each portion metallurgically alloy-bonded during
casting to an adjacent portion or portions along the longitudinal extent of the strip
(30). In the method and apparatus for producing such strip (30) a stream of molten
metal is delivered onto a casting surface (18) from a first crucible (10) and at least
one additional dissimilar stream of molten metal is delivered onto the casting surface
(18) from a second crucible (11) such that a peripheral edge of the dissimilar stream
contacts a peripheral edge portion of an adjacent dissimilar metal to create a metallurgical
alloy-bond therebetween during casting.
