Description

Using the method of thermosorptional spectroscopy the effect of grain size and cold deformation on helium evolution from the alloys 03Kh20N45M4BCh (ChS-42) and 03Kh20N45M4BRTs (ChS-43) in the process of annealing is investigated. It is ascertained that both the decrease in grain size and preliminary cold deformation (5 %) of the samples suppress considerably helium evolution from ChS-42 and do not practically affect helium evolution from ChS-43. Consequently, low-temperature stage of helium evolution from samples (approximately 280 deg C) is related to helium, initially present on the grain boundaries near the surface
