Abstract
1315652 Heat-recoverable alloys; couplings; electrical contacts; formers FULMER RESEARCH INSTITUTE Ltd 29 April 1970 [1 May 1969] 22372/69 Headings B3A and B3V [Also in Divisions C7 and G1] A method of making an article from a heatrecoverable alloy, which alloy when suitably heat treated in one shape and caused to deform at an appropriate temperature into another shape partially recovers its first shape upon sufficiently raising the temperature of the article, comprises the step of applying a strain to the alloy in its high temperature phase which produces a stress and induces a desired shape change in its low temperature phase. The alloys may be deformed by either working in the high temperature phase by heating whilst applying a restraint, or working in the low temperature phase whence on cooling they undergo a shear transformation to a martensite or retain the high temperature phase as quenched but transform by shear on cold working. The phenomenon is known to occur with certain Ti-Ni alloys, Au-Cd alloys, In-Th alloys and has been found to occur with Mu- 5 to 50 wt. per cent Cu, U- 2 to 7 wt. per cent Mo, U- 3 to 11 wt. per cent Nb, and U- 2 to 7 wt. per cent Re. Examples of such articles include tubes in couplings, which tubes change shape to grip connectable elements together, formers or dies on which plastics or metal sheet can be shaped, thereafter the former or die being caused to shrink away allowing the removal of the shaped sheet and the former or die is then caused to revert to its original shape for a next operation,and temperature-responsive elements in switching devices. Such a device (4) (not shown) comprises three contacts (10)-(12) with electrical connection between the contacts (10), (11) being made by bent strip (13) at one temperature and between contacts (10), (12) at another temperature.
