AbstractรA model is proposed for the yield stress of ultra-ยฎne grained materials based upon Coble creep. Using Coble creep with a threshold stress for ยฎner grains and conventional HallยฑPetch strengthening for larger grains, an analytical relation is derived for the yield stress as a function of grai

The strain-rate sensitivity of flow stress (3X7 ร 10 ร3 s ร1 3X7 ร 10 ร4 s ร1 ) in fine-grain polycrystalline copper has been studied over the entire stressยฑstrain curve at room temperature. It is observed that the yield stress varies with mean grain diameter (32 to 59 mm) in accord with the Hall-Pe
Tensile stress strain data for 99.999". copper at room and liquid nitrogen temperature as a function of grain size are presented together with some microstructural observations made by transmission electron microscopy. It is shown that the flow stress data. at constant strain may be expressed in ter
