Abstract
A process for the manufacture of a solid gas and vacuum tight join between components of different physical properties using a joining element comprising a memory alloy whose memory effect gives rise to the necessary contraction or dilatation stress, in particular for the connection of a hollow body of ceramic material to a metallic object. Joins comprising a memory alloy joining element result from such process having a groove and steps and at least one further metallic or non-metallic component, in particular a hollow body.
Claims16
A process for the manufacture of a solid and tight join between components using first and second joining elements which comprises:
- forming at least one annular dove-tail groove in said first joining element, said first joining element comprising a heat releasable, metallic, shape memory effect alloy;
- pressing said second joining element into said at least one annular groove of said first joining element;
- and
- shrinking by heating said first joining element so as to form said solid and tight join due to shape memory effect of said at least one groove of said metallic, shape memory effect alloy.
