Microstructures of Deformed Alpha Plutonium.

Year: 1969

Type: report

Abstract: The effect of temperature, strain rate, and total strain on the deformation mode of high purity cast alpha plutonium was determined.Deformation was predominantly by grain boundary -4 sliding at 110 °C and at a strain rate of 10 per min, whereas slip was the major deformation mode at -10 °C and 10 ' per min.Deformation at intermediate temperatures and strain rates was by a mixture of grain boundary sliding and slip.Recrystallization occurred concurrently with deformation only after a critical strain was reached.The critical strain decreased with increasing temperature and was independent of strain rate -1 -4 in the range of 10 to 10 per min.Strains of 14, 6, and 3 pet were required at 105, 110, and 120 °C, respectively^ before recrystallization started.Deformation by twinning was insignificant.
