Abstract

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.
