    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.

    摘要： Zirconium-titanium alloys containing at least one of the transition metal elements of iron, cobalt, nickel and copper are disclosed. The alloys consist essentially of about 1 to 64 atom percent titanium plus at least one element selected from the group consisting of about 15 to 27 atom percent iron, about 15 to 43 atom percent cobalt, about 15 to 42 atom percent nickel and about 35 to 68 atom percent copper, balance essentially zirconium plus incidental impurities, with the proviso that when iron is present, the maximum amount of titanium is about 25 atom percent, when cobalt is present, the maximum amount of titanium is about 54 atom percent and when nickel is present, the maximum amount of titanium is about 60 atom percent. The alloys in polycrystalline form are capable of being melted and rapidly quenched to the glassy state. Substantially totally glassy alloys of the invention evidence unusually high electrical resistivities of over 200 .mu..OMEGA.-cm.
