Connected component having two workpieces of different coefficients of expansion has one rigid connection and slot recesses in one workpiece for projections on other

摘要

The connected component consists of two workpieces (1, 2) with difference coefficients of thermal expansion. There is at least one rigid connection between them. As a further connected, one of them (1) has cruciform recesses (3) to take cruciform projections (4) on the other one (2). The recesses all run towards the rigid connection.
