A number of ceramics, metallic compounds, and ceramic-metal composites were successfully hot pressed into the shape of die inserts. Steels were extruded through several of these for the purpose of evaluating the materials or to study methods of supporting the die inserts. Refractory metal inserts were also used in similar tests. Hot pressed inserts consisting of 80 vo1% Al/sub 2/O/ sub 3/--10 vol% W and 80 vol% ThO/sub 2/--10 vol% W cracked but did not erode. Sintered molybdenum inserts flowed excessively, whereas sintered tungsten inserts flowed to a lesser degree. A hard die casing with a slight shrink fit appears to be the most satisfactory method of support. (auth)
