Observations on Historical and Contemporary Developments in Superplasticity
, 1990 The history of superplasticity is reviewed. The first scientific observation of superplasticity dates back to 1912. Sporadic reports of subsequent observations appear in the literature up to the review by Underwood in 1962.
