| titleOfInvention | METHOD FOR DUCTILITY IMPROVEMENT OF HIGH-MELTING METALS |
| abstract | From high-melting metals, such as tungsten and molybdenum, oxygen and potassium impurities are to be expelled in accordance with the task, because they are the cause of Sproedbruch's transformation. This is done according to the invention by the addition of an excess of zinc stearate to the metal powder. After shaping and sintering, with the carbon of the zinc stearate causing deoxidation and the zinc forming a slightly volatile intermediate phase with the potassium, metal parts with the desired properties are obtained. The invention is applicable in powder metallurgy. |
