<p>Feed material for use in producing a thixotropic alloy comprisingpellets (10) in the form of a solid cylinder having a length to diameter ratio in the range of from 1:1 to 2:1 and a maximum length of preferably 0.250 inch. In addition, the pellets optionally exhibit one of: a substantially triangular shaped side profile, a substantially trapezoidal shaped side profile, or a semi-trapezoidal side profile. The pellets are produced by extruding a metal alloy or composite into an extruded stock material having a substantially uniform cross-sectional shape along a longitudinal axis, and severing lengths of the extruded stock material. The pellets are further heated and sheared in an extruder apparatus to a temperature above the solidus temperature, to form a thixotropic alloy.</p> |
