Abstract
A casting wheel quench surface rapidly solidifies molten alloy into strip having a microcrystalline or amorphous structure. The surface is composed of a thermally conducting alloy having a homogeneous microstructure consisting of fine equiaxed recrystallized grains. The grains exhibit a tight Gaussian grain size distribution.
Claims8
A quench surface for rapid solidification of molten alloy into strip having an amorphous structure, said quench surface being composed of a copper based, thermally conducting alloy having a microstructure consisting of fine, equiaxed, recrystallized grains, the average size of said grains being less than 200 .mu.m and none of said grains being larger than 500 .mu.m, said grains having a tight Gaussian grain size distribution.
