Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation, for a variety of purposes. Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying radiation effects, eradicating insects through sterile male release programs, or calibrating thermoluminescent dosimeters (TLDs).
The exposure can originate from various sources, including natural sources. Most frequently the term refers to ionizing radiation, and to a level of radiation that will serve a specific purpose, rather than radiation exposure to normal levels of background radiation. The term irradiation usually excludes the exposure to non-ionizing radiation, such as infrared, visible light, microwaves from cellular phones or electromagnetic waves emitted by radio and television receivers and power supplies.
"Austenitic steels (fcc) irradiated and tested at high temperatures show no increase in either yield".
I understand that irradiation hardening occurs because the movement of dislocations is hindered by the presence of defects. This phenomenon can be observed in both body-centered cubic (bcc) and...
When comparing FCC (Face-Centered Cubic) and BCC (Body-Centered Cubic) metals, I typically consider their packing efficiency and the number of active slip planes. FCC structures exhibit higher packing efficiency and a greater number of active slip planes compared to BCC structures.
