Abstract:
A copper-nickel-silicon quench substrate for rapid solidification of molten alloy into strip, having a two-phase microstructure with copper rich regions surrounded by a network of nickel silicide phases, said quench substrate being composed of a thermally conducting alloy and said structure being substantially homogeneous, said thermally conducting alloy being a copper-nickel-silicon alloy consisting essentially of about 6-8 wt % nickel, about 1-2 wt % silicon, about 0.3-0.8 wt % chromium, the balance being copper and incidental impurities, and wherein the cell size of the two-phase structure ranges from 1-1000 &mgr;m, and said copper rich region is surrounded intimately by a network of nickel silicide.
