| 摘要 |
The present invention comprises a creep resistant lead base alloy characterized by finely dispersed intermetallic compound and containing, by addition, at least one solid soluble alkali or alkaline earth metal component prealloyed with lead which is selected from Groups IA and IIA of the Mendeleeff Periodic Chart of the atoms, and at least one metalloid component selected from Group VB of said atomic chart, the balance being essentially lead, and a method of preparing said alloy. The method of making said creep resistant lead base alloy comprises: (a) dissolving the selected alkali or alkaline earth metal in molten lead, (b) particulating the mass from the molten form to provide a prealloy, (c) intimately and homogenously contacting said solid, particulate prealloy with the metalloid component, and (d) diffusing said metalloid component into the prealloy at an elevated temperature to form an essentially insoluble intermetallic compound finely dispersed throughout a final creep resistant lead base alloy.
