摘要:
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.sup.-1.
