    Abstract

    The residual stresses in a gas tungsten arc weld of the single crystal superalloy CMSX-4 have been examined using neutron diffraction techniques. The longitudinal component of the residual stress field was found to be dominant, reaching a value of 650 MPa in the weld zone. In order to rationalise the results, finite element modeling was carried out. Strategies are suggested for the manufacture of a single crystal weld that is not subject to strain-induced recrystallization during heat treatment.
