Abstract

Four cylindrical steel bars of 2 cm diameter and 20 cm height were subjected to compression cycles each of them consisting of a loading phase at fixed stress rate followed by a rapid stress release. Different compression rates were used for the same sample. The area surrounding the loaded samples was monitored in order to check whether ionizing particles were emitted. To this aim, three ZnS(Ag) detectors, a Geiger counter, and some polycarbonate CR39 detectors of alpha particles were used. An 3 He proportional detector of neutrons was also used. The whole set of results is discussed and proposed as an evidence of alpha particles emission from the bars during the compression cycles.
