Kinetic metallization offers certain advantages over hard chrome and high-velocity oxyfuel thermal spray coatings, especially when elevated process temperatures would degrade the coating or part.

Development of new, radiation-tolerant materials that maintain the structural integrity and safety margins over the course of a nuclear power reactor’s service life requires the ability to predict degradation phenomena. Modern post-irradiation examination methods make use of specialized high-flux test reactors and dedicated characterization facilities to limit occupational exposure and prevent the spread of radioactive contamination. This article illustrates the use of these advanced techniques to characterize precipitates in neutron-irradiated Fe-Cr-Al alloys.

In the thermal spray workplace hazards appear throughout the coating operation, from incoming orders to final inspection. This article introduces a discussion of safety practices and oulines methods to address dust and fume hazards.

As industrial infrastructure continues to age, the risk of corrosion-related incidents becomes greater, increasing the need for detailed analysis of residual elements in steel framework and equipment. X-ray fluorescence is seeing greater use due to new smaller, lightweight equipment designs.

Induction Heating and Heat Treatment, Volume 4C of the ASM Handbook, was developed to serve as a comprehensive resource on induction thermal processes to meet the needs of the induction heating and heat treating communities. This article reviews the topic coverage of the volume.

High-speed rotating components in gas turbines, flywheels, and turbo machinery can be a lethal threat in the event of a failure due to the energy they possess. To assess the risks associated with such failures, rotor assemblies can be evaluated by spin testing although there are inherent risks in the tests themselves. This article discusses these risks and explains what can be done to minimize the potential dangers of high-speed performance testing.

Nanostructured tungsten-tungsten carbide chemical vapor deposition (CVD) coatings provide a practical, technical, and commercially viable alternative to hard chrome plating for aircraft components.

Finite element representations of crash test dummies are widely used in the simulation of vehicle safety systems. The biofidelity of such models is strongly dependent on the accurate representation of the nonlinear behavior of constituent rubber, plastic, and foam materials. This article presents a simulation workflow in which material parameters are more easily optimized and demonstrates its use in the calibration of a viscoelastic model for the behavior of rubber-like materials in a side-impact dummy.

As a regular contributor to the HTPro eNewsletter, Professor Induction answers a wide variety of questions regarding induction heating and heat treating. Included here are three recent challenges and solutions.

A new high-strength steel developed for cold stamping addresses the challenges presented by materials traditionally used to manufacture electric vehicle components.

This article reviews the current state of thermal spray nanocomposite coating technology and assesses commercially available feedstock materials as well as those in development.

Metal-matrix composite (MMC) materials are being developed at the University of Wisconsin-Milwaukee for a diverse range of automotive applications from pistons and cylinder liners to exhaust manifolds and chassis sections. The ability to tailor not only the properties but also the functionality of MMCs gives automotive engineers a powerful new tool in dealing with increasingly strict fuel economy standards.

Beyond automotive, aerospace, and medical materials innovations, research and development of advanced materials and processes for sports and recreation activities is one of the most exciting areas for today’s materials scientists and engineers.
