PROBLEM TO BE SOLVED: To provide a lubricant for a metallurgical powder composition. SOLUTION: A manufacturing method of a sintered product comprises the steps of: (a) producing the metallurgical powder composition by mixing a metal powder and the lubricant; (b) preheating the metallurgical powder composition to a predetermined temperature; (c) compacting the heated metallurgical powder composition in a heated tool; and (d) sintering the compacted metallurgical powder composition. In this manufacturing method, the lubricant contains a polyolefine-based polymer, which has an average molecular weight Mw of 1,000-10,000. COPYRIGHT: (C)2008,JPO&INPIT |
