<p><P>PROBLEM TO BE SOLVED: To provide an Mo compact which can manufacture a powder compact having a three-dimensional shape that suppresses the coarsening of crystal grains, prevents the decrease of strength, also enhances durability and reliability compared to those of a conventional one and has strength at high temperature, inexpensively, efficiently and at a high yield, and to provide a method for manufacturing the same. <P>SOLUTION: The Mo compact 4 having the three-dimensional shape is formed by arranging a core 2 in a forming vessel 1, filling a space between the forming vessel 1 and the core 2 with an Mo powder 3, and treating the powder with a HIP process. The method for manufacturing the Mo compact having the three-dimensional shape includes filling the space with the Mo powder 3 or a mixture powder 3 in which one or more of the Mo powder, an Nb powder, a W powder and a ceramic powder having a high melting point are mixed, treating the powder with the HIP process, and then dividing the obtained Mo compact 4 into two pieces. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
