Title: Sintered refractory metal with improved porosity resistance at weld zone
Inventor: ARATA YOSHIAKI
IPC: C22C27/04
Filed: 1981-12-01
Abstract: PURPOSE:To reduce the porosity of a sintered refractory metal of Mo, Nb or Ta powder at the weld zone by adding an adequate amount of BN inhibiting the growth of crystal grains to the refractory metal. CONSTITUTION:BN powder is added to Mo, Nb or Ta powder by an adequate amount below the solubility, and they are mixed, compressed with a press, presintered and sintered. The sintered body is forged, rolled and mechanically worked. When the resulting sintered refractory metal is subjected to electron beam welding, since the growth of the crystal grains of the metal at the weld zone is inhibited by the added BN during the welding, the crystal grains at the weld zone become remarkably fine. Most of a gaseous component and Mo or Mo oxide vapor escape from the metal through the grain boundaries during the welding, so the porosity at the weld zone can be reduced to a very low level.
