Irridating aluminum

Radiological control surveillance is required whenever the shield plug is removed for sample handling., located in the Fuels and Applied Science Building (FASB), expands gamma irradiator capability by introducing the option of "in-motion" type irradiation experiments.The Gamma Irradiator Test Loop assists researchers in studying the effects of radiation on the structural integrity of solid and liquid materials.The instrument delivers a radiation dose from Co-60 source (~4 k Gy/hr as of Aug. Two experimental options currently are available: (1) static, where sealed vials containing non-rad or rad materials are irradiated, and (2) dynamic, where analyte liquids are irradiated while being continuously circulated through a test loop located inside the irradiator.

Now we are seeing a new trend: aluminum alloys are now driving the PMI programs in automotive manufacturing.

The presence of helium atoms in metals is crucial to metal performance because precipitated bubbles from helium can substantially deteriorate their mechanical properties, especially for metals at high homologous temperatures ( is the melting temperature).

In this case, drastic embrittlement occurs because of the formation of helium bubbles at the grain boundary [1, 2].

The structure of Topaz is controlled by a chain like structure of connected irregular octahedrons.

These octahedrons have an aluminum in the middle surrounded by four oxygens.
