Process for inducing a state to an article, made from a memory shape alloy with two reversible memory states. |
摘要 |
<p>The shaped article with the final shapes and dimensions forming the first shape memory state is subjected to a heat treatment with a view to bringing this article into a crystallographic phase of austenitic type and then to a cooling. The article is then subjected in at least one deformation zone to a so-called education process consisting in imposing a series of thermal and/or mechanical stresses on the said article, over at least one cycle. The stresses are capable of resulting in distortion of the article to bring the latter into a shape position close to its second shape memory state in a martensitic crystallographic state, and then in allowing the article to return to its first shape memory state during a return of the article to the austenitic crystallographic state. Application to electrical contact elements. <IMAGE></p> |
