Ultrasonic Piezonuclear Reactions in Steel and Sintered Ferrite Bars

We report the results of piezo-energy emissions in the form of neutron bursts measured during the application of ultrasounds to sintered ferrite (alpha-Iron) and steel bars using an original experimental device. The measurements, carried out by HDS-100GN and by a Microspec2 neutron probe, confirmed neutron emission repeatability from inert iron-rich media and the absence of gamma radiation. In addition, energy spectra of neutron emission during the application of ultrasounds are shown as well. After neutron detection, Energy Dispersive X-ray Spectroscopy (EDS) analyses were conducted, showing semi-quantitative evidences of iron decrease and the possible occurrence of nuclear reactions of a new type in correspondence to meso-craters ( burns) localized on the external surfaces of the bars. Finally, similar evidences may be observed at the Earth's crust scale where well distinguishable neutron emissions and anomalous chemical changes in correspondence to major earthquakes and micro-seismic activity may be considered to explain the significant iron depletion characterising seismic areas and the Earth's crust evolution.
