Abstract (en)
[origin: WO9833610A1] A semi-solid metal forming process using a cast billet and having the following steps: 1) heating the cast billet to a temperature above its recrystallization temperature and below its solidus temperature; 2) extruding the cast billet into an extruded column; 3) cutting the extruded column into at least one billet; 4) heating the billet from step 3 to a semi-solid state; and 5) squeezing the billet from step 4 into a cavity in a metal forming die set to form a part.
