Abstract
Stainless iron-base alloy having a total shape memory effect consisting, after a given cold mechanical deformation, in a recovery of the initial shape by heating, characterized in that its composition by weight is the following: PA1 9 to 13% chromium, PA1 15 to 25% manganese, PA1 3 to 6% silicon, the remainder being iron and residual impurities resulting from the fusion of substances necessasry for producing the alloy, the proportions of the elements satisfying the relation: EQU 1.43(%Si)+1 (%Cr) .ltoreq.17. The invention also provides a method for producing this alloy.
