    • ‘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.’
    • ‘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.’

noun

Metallurgy
  • A superplastic metal or alloy.

    • ‘The age of superplastics has its origins in the last decade or so and is largely a result of fundamental insights into the nature of matter, most especially the electronic and physical properties of monomers, which are small groups of molecules that can be linked into long chains known as polymers.’
