One of the most known intelligent material is nitinol, which offers many functional advantages over conventional implantable alloys. Applications of SMA to the biomedical field have been successful because of their functional qualities, enhancing both the possibility and the execution of less invasive surgeries. The biocompatibility of these alloys is one of their most important features. Diffe...

Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...

This paper describes the use of microdischarges between lithographically defined features as tools for further processing. Techniques based on the use of microplasmas can facilitate the microfabrication of complex microstructures (with dozens of structural levels) using just two masking steps, whereas microarcs can be used to increase the diversity of used in microstructures to WC-Co super-hard...

Shape memory alloys are well recognized functional and smart materials, which have been exploited to develop intelligent structures and devices in many fields. Of particular importance is its exciting application in the field of biomechanical engineering. In addition, further potential applications of shape memory alloys are being investigated, such as shape memory alloys-based functional compo...

STATEMENT OF PROBLEM The increase in the use of metal-ceramic restorations and a high prevalence of porcelain chipping entails introducing an alloy which is more compatible with porcelain and causes a stronger bond between the two. This study is to compare shear bond strength of three base-metal alloys and one noble alloy with the commonly used VMK Master Porcelain. MATERIALS AND METHOD Three...

The shape memory alloys present, in the high temperature phase, a super-elastic behaviour : during a super-elastic test, the martensitic transformation is induced by the stress, and a large reversible deformation is observed. With a single crystal, the maximum superelastic deformation reaches 8 to 10%. During the tensile test on a single crystal, only one variant of martensite is induced in the...

In an effort to address the limitations on high-power accelerator target performance prompted by the elevated dose levels and the associated irradiation damage, an experimental study has been conducted to explore interesting new alloys and composites under the influence of protons and neutrons. Material irradiations were performed using the 200-MeV protons of the BNL Linac operating with an eff...
