<p>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.</p> |
