| 摘要 |
PURPOSE: To efficiently produce square pipes. CONSTITUTION: Aluminum powder and neutron absorber powder are mixed and a preliminary mold is formed by cold static hydro-pressure molding method. Then, the preliminary mold is vacuum-sintered in no pressure condition. After the sintering, the billet is induction-heated to hot-extrude and form a square pipe.
