Title: Failure assessment of a driven shaft of an extrusion gear pump

Abstract: The paper deals with the investigation of failure of a driven shaft made of BS 970-1991 Series 080 M40 (BS 970-1955 Series En 8) grade steel. It broke after 1100 h run while pumping out liquid polythene under normal operating condition. Metallurgical investigation reveals Widmanstatten pattern and very coarse grains enveloped with ferrite, though the chemical and physical properties of the material are satisfactory. Presence of such microstructure due to elevated finishing temperature of the forging process causes brittle fracture. The suggested remedial measure is to keep the finishing temperature just above the lower critical temperature.
