摘要： A 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. The average size of said grains being less than 200 mum and none of said grains being larger than 500 mum.
