SUPERPLASTISKA METALLEGERINGAR MED HOEG DEFORMATIONSHASTIGHET |
摘要 |
<p>Superplastic metal alloys having a high defromation rate are disclosed. Their structure is characterized by the presence of at least two principal constituents, the major one of which is of a particulate globular or elongated shape while the minor one surrounds the first completely or partially in the form of a particle on the boundry surface of the major constituent which is less than 10 mu m thick. This invention can be applied to the shaping of alloys in the superplastic state at a high deformation rate above 100% min-1.</p> |
