The creep often occurs differently along different crystalline orientations in polycrystalline engineering alloys, therefore generated internal stress between different grain orientations. However, it is not well understand how this occurs under different boundary conditions including constant load, constant strain and elastic follow-up control. This work describes a new designed rig for conducting stress relaxation as well as elastic follow-up creep experiments on 316H stainless steel in the ENGIN-X neutron beam line. Three short term measurement results show that the internal stresses between different grain families were found to be constant during creep tests irrespective of different boundary conditions. Elastic follow-up has no effect on the redistribution of lattice strains. The successful of this commissioning give us strong evidence that the long term creep experiments in a neutron diffraction beam line can be achieve in the near future.
