Fundamental radiation effects parameters in metals and ceramics

Radiation Effects in Nuclear Ceramics

Due to outstanding physicochemical properties, ceramics are key engineering materials in many industrial domains. The evaluation of the damage created in ceramics employed in radiative media is a challenging problem for electronic, space, and nuclear industries. In this latter field, ceramics can be used as immobilization forms for radioactive wastes, inert fuel matrices for actinide transmutat...

New Nissan to feature complex aluminum castings The new Nissan GT-R features aluminum inner-door and rear-seat structures made from Alcoa’s proprietary vacuum die casting process (AVDC) at the company’s plant in Soest, Germany. Both components also feature new proprietary alloys developed by Alcoa. The new C-446 alloy, in combination with the unique advantages of the AVDC process, enabled Alcoa...

Crystallographic Texture in Ceramics and Metals

Preferred crystallographic orientation, or texture, occurs almost universally, both in natural and man-made systems. Many components and devices in electronic and magnetic systems are fabricated from materials that have crystallographic texture. With the rapidly increasing use of thin film technology, where sharp axisymmetric crystallographic texture normal to the film plane is frequently obser...

Fundamental Tribological Properties of Ceramics

In situ TEM of radiation effects in complex ceramics.

In situ transmission electron microscopy (TEM) has been extensively applied to study radiation effects in a wide variety of materials, such as metals, ceramics and semiconductors and is an indispensable tool in obtaining a fundamental understanding of energetic beam-matter interactions, damage events, and materials' behavior under intense radiation environments. In this article, in situ TEM obs...
