Abstract
The present invention is directed to a method and the associated apparatus for producing rapidly solidified materials by spill chilling. The feed stock can include any of a variety of materials including a high melting point and reactive materials, as well as conventional iron, aluminum, copper and transition base commercially available alloys. A support surface is provided for the solid feed material. Means are provided for both globally and locally heating the feed material. The heating means can include resistant heaters, induction heaters, arcs, electron beam and plasma heaters. A focused energy source such as an electron beam, a laser beam, ion beam or an electric arc can be provided for locally heating the material. The molten feed material is spill chilled onto a moving chill surface. The moving chill surface can be in the form of a continuous belt or the rim of a rotating wheel. It is preferred that the chill surface be cooled and it is further preferred that cooling be provided to the side of the surface which is contacted by the spilled material. In a preferred embodiment means for replenishing the feed material and means for advancing the feed material into the pool so t…
