Objective
The purpose of the project is to manufacture Shape Memor y alloys for electrical contacts. The material to be used is made of TiNi(x); Cu, Zu, Al and Cu Al Ni. Four specialized laboratories will be involved in this project, each one doing one part of the specialized work: - Souriau manufactures electrical contact material; - CESUS and Nivarox will provide wires and strips; - E.N.S.C.P. will be involved in the more fundamental aspects. The objective of the research is to reach a systematic approach of crystalline structures that develop in S.M.A. during thermal and mechanical cycles, something which has not been achieved until now. The economic interest lies in the fact that it will be possible to define industrial processes which are optimized at the level of cost, quality and reproducibility of the materials.
The purpose of the project is to manufacture titanium nickel and copper zinc aluminium shape memory alloys for electrical contacts. The objective of the research is to reach a systematic approach of crystalline structures that develop in shielded metal arc (SMA) during thermal and/or mechanical cycles. The economic interest lies in the fact that it will be possible to defineindustrial processes which are optimised at the level of cost, quality and reproducibility of materials.
A special X-ray diffractometer has been assembled, in which the samples can be stressed up to 10N, and gas heated or cooled from 200 C to 180 C. Strips of copper zinc aluminium titanium nickel alloys have been investigated in both as received or trained by thermal and/or mechanical cycles states. It has been shown that in every case, the Austenite and Martensite structures are much more complex than trivial body centred cubic (BCC) structure and closed packed polytypic structure. Widely diversified structures appear in the as received and prime cycled training states. These evolutions during training show a stabilisation which began to occur after 20 training cycles and is completely achieved after 50 training cycles.

Funding Scheme
Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
