发明名称 METHOD OF SUCCESSIVELY EXTRUDING METAL POWDER
摘要 <p>A method of successively extruding a metal powder in which a satisfactory bonding strength is obtained between a preceding extrudate extruded first and the succeeding extrudate subsequently extruded. The method for successively extruding a metal powder comprises: a step in which a metal powder (3) which has been heated is charged in the powdery state into an extrusion mold (1) having an extrusion opening; a primary extrusion step in which the metal powder (3) in the mold (1) is extruded with an extrusion tool (4); a step in which subsequently to the primary extrusion step, an additional metal powder (6) which has been heated is charged in the powdery state into the mold (1) and put on a compact (5b) of the metal powder remaining therein in the compacted state; and a secondary extrusion step in which the compact (5b) and additional metal powder (6) in the mold (1) are extruded with the extrusion tool (4).</p>
