Low Shrinkage, Coarse‐Grained Tantalum

A maximum pressure of 50 MPa resulted in a geometrical density of 7.88 g cm −3 while a pressure of 150 MPa with a cyclic pressure increase densified the composite up to 8.56 g cm −3. This value corresponds to a relative density of 73.9 % if a composition of 60 vol% tantalum and 40 vol% alumina is assumed.
