The continually increasing demand for new energy will likely be met through a combination of traditional and emerging energy platforms. While technology needs for traditional oil and gas production differ greatly from the needs of emerging power generation platforms, such as solar, wind, fuel cells, and batteries, a common need among all these sources or energy is advanced materials. Tantalum surface alloys enable advancements in traditional and new energy production methods.

This article describes research at Los Alamos National Laboratory that is aimed at building a coupled experimental and computational methodology that supports the development of predictive damage capabilities by: (1) capturing real distributions of microstructural features from real material and implementing them as digitally generated microstructures in damage model development, and (2) distilling structure-property information to link microstructural details to damage evolution under a multitude of loading states.

An ultrafast, efficient industrial-scale boriding process can drastically reduce costs, increase productivity, and improve the performance and reliability of a variety of machine parts. This article describes a novel, environmentally friendly technology that enables treating thousands of industrial components in one batch, without creating solid or liquid waste and gaseous emissions.

Optical or light microscopy uses the visible or near-visible portion of the electromagnetic spectrum and is one of the oldest characterization techniques. With any cold spray coating, it is the first characterization process used to evaluate and optimize process variables.

Conventional manufacturing from wrought bar stock typically involves extensive machining, creates significant material waste (scrap metal), and requires numerous steps to obtain the final part geometry. As a more efficient alternative, powder metallurgical (PM) processes are now available to cost effectively fabricate both simple and complex shapes with minimal material waste. Combustion driven higher pressure powder compaction (CDC) for near-net or net shape manufacturing was recently developed. It offers a unique way of forming near-net or net shape high-density powder metal components both cost effectively and at relatively higher compaction pressures than other PM processes.

Using a physical vapor deposition process to manufacture medical device components reduces post-processing time and improves materials properties. This article addresses metallic sputter deposition technologies for Nitinol medical devices.

A new fusion cladding process that uses high-intensity arc lamps can produce pinhole free, smooth, uniform coatings as thick as 15 mm from various feedstock materials. This article briefly describes the process and the corrosion, wear, and high-temperature behavior of fusion claddings designed for oil and gas pipelines and related components.

The invention of the single crystal jet engine blade under Frank Versnyder and a team of scientists at the Pratt & Whitney Division of United Technologies is considered one of the 50 greatest advances in metallurgical history.

The corrosion of structural materials and control of coolant chemistry are key factors that impact the lifetime of nuclear reactors and the development of future reactors. This article reviews corrosion issues in four reactor concepts that use vastly different coolant types: light water reactors, lead fast reactors, high temperature gas-cooled reactors, and fluoride salt-cooled high temperature reactors.

The utility of cluster ion beams for x-ray photoelectron spectroscopy (XPS) analysis is just beginning to be explored, making a range of materials accessible that previously could not be analyzed. When combined with a monatomic source, these cluster ion beams will become an essential tool for any materials analysis laboratory. A new monatomic and gas cluster ion source for XPS instruments uses argon gas cluster sputtering to clean surfaces and create depth profiles for a growing class of advanced materials that include both hardened inorganic and softer organic materials.

Custom equipment designed for the deposition of exotic materials allows advanced coating solutions and ceramic matrix composites to be utilized for applications in automotive, aerospace, defense, energy, and the farthest reaches of space. This article describes custom systems for chemical vapor deposition and advanced materials processing.
