A new two-dimensional theoretical model for creep in materials with soft boundary phases was developed using fluid transport equations. The theoretical model is developed for a two-phase, isothermal system consisting of rigid rectangular grains surrounded by a matrix of viscous Newtonian fluid. This model predicts shape changes for a total system which includes hydrostatic pressure and free edge effects which can occur during hot-pressing or during creep. A plane strain experimental apparatus was constructed to obtain results for comparison with the theoretical model. The fluid phase used in the experimental study was an alloy of tin, lead, bismuth and cadmium commonly known as Wood's metal (melting point, 68$\sp\circ$C). Due to a lack of published creep data for this alloy, compression creep tests were conducted on cylindrical specimens the results of which display Newtonian fluid behaviour, but with a stress sensitive mechanism change during slow deformation at 35$\sp\circ$C.Dept. of Chemistry and Biochemistry.
