Definitions

  • This invention relates to a new structure of metal alloys having the superplastic state in the solid state, these alloys being made either of Zircoloy-4 or of brass Cu-Zn 36.
  • each constituent can be either a phase in the crystallographic sense (in which case the alloy is at least two-phase), or distinct micrographic constituents formed by several phases (solid solution + fine precipitates, eutectics, eutectides , etc ...) or both.
  • a tensile specimen 0 2.5 mm was machined and brought to 850 ° C, by HF heating, during a hot tensile test.
  • a 0 4 mm brass ⁇ wire (CuZn 36 according to French standard AFNOR A51-101 April 76), initially hardened by 96%, underwent rapid heat treatment in the two-phase ⁇ + ⁇ range. This last treatment carried out by HF heating consists of a rise to 790 ° C. in 3 seconds and a hold of 2 sec. at this temperature before water quenching.
  • the deformation rates thus obtained are at least equal to 30 times those observed on conventional superplastic materials and more than three times greater than those of materials with transient induced superplasticity.
