Abstract
Snoek pinning of dislocations due to oxygen in tantalum was investigated using internal friction and simultaneous deformation techniques. The magnitudes of the pinning in the two oxygen concentrations used (5 ppm and 100 ppm) were found to be approximately 20 kg/cm2 and 150 kg/cm2, respectively. This shows that Snoek pinning can contribute a significant fraction of the yield stress in material with high concentrations of dissolved interstitials.This publication has 7 references indexed in Scilit:
