One of the most important factors to consider when evaluating a specialty metal for use in valves, fittings and instrumentation is its corrosion resistance or corrosion rate of the metal in the target media. Each material discussed here has its own niche, and depending on the processing environment and the needs of the application, the metal’s strengths and weaknesses may or may not be suitable. In...

Cast parts, such as engine blocks, are typically made by pouring molten metal into so-called cores — sand-based molds that have internal passages for the component to be cast. Such casting cores are typically made by reacting sand with organic binders in a curing process. In recent years, industry has been seeking alternatives to organic binders to avoid releasing toxic emissions during curing. Last...

The exceptional properties of carbon nanotubes (CNTs), such as high tensile strength and high thermal and electrical conductivities, have suggested a number of applications, including lightweight materials for ballistics protection, actuators for muscles or artificial muscles, filaments for light sources, electrodes, super-capacitors, and flow sensors. So, many researchers have tried to prepare macroscopic...
