Description

Room temperature tensile tests were conducted on Ni-20Cr-2ThO2 alloy single crystals to determine the value of the Orowan stress and to compare it with the apparent threshold stress for creep. It was found that the observed creep threshold does not correspond with the Orowan stress and that creep occurs below the Orowan stress by some mechanism other than Orowan bowing
