superplastic Syllabification: su·per·plas·tic
Pronunciation: /ˈso͞opərˌplastik/

Definition of superplastic in English:


(Of a metal or alloy) capable of extreme plastic extension under load.
Example sentences
  • The need to use elevated temperatures for deformation of magnesium has lead in the past to the production of complex pressed shapes reminiscent of those obtainable in superplastic alloys.
  • An entirely new range of cost and weight saving components for both airframes and engines are now being developed using superplastic forming and diffusion bonding processes, for which this alloy is ideal.
  • Furthermore, prograde metamorphism can result in weakening and superplastic behaviour of the rocks affected, as fluid pressure rises, minerals are weakened, and the grain-boundary structure is transformed by breakdown and growth.
