Aluminum-silicon (Al-Si) alloys have good castability in combination with high corrosion resistance, thermal conductivity, and specific strength, making them a strong candidate for many automotive applications. This article describes the processes used in the production of die-cast AlSi9Mg engine brackets for Volvo trucks, the effects of solution treatment temperature on Si particle size, and the benefits of Mg additions on yield strength and heat treatability.

This case study describes how electron-beam melting, a powder bed additive manufacturing technology, helped reduce the cost and material scrap associated with the production of Ti-6Al-4V brackets used in the hot side of the engine on Lockheed Martin's Joint Strike Fighter.

Thixoforming is a hybrid technology used to manufacture net shape components from a variety of alloys ranging from low melting temperature aluminum and magnesium to steel and Co-base alloys.

Difficulty in clearly and quantitatively answering questions concerning a component or product failure can lead to courtroom debates, arguments, and battles. The case studies in this article identify and describe technical procedures to assist with explaining complex situations and thereby assist in solving failure analysis problems and resolving legal disputes.

Novel methods for altering the mechanical properties of functionally graded orthodontic medical devices leads to new applications. This article highlights recent applications of selective vaporization to enable functional grading of shape memory alloys in medical devices for the dental industry.

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.

This case study measures residual stress on a truck axle housing as it goes through the manufacturing process.

The largest and heaviest component in a car is the body structure, so it was only natural to make this the focus of advanced R&D in the 1970s and 1980s for aluminum auto body applications.

Although the widespread use of titanium alloys is constrained by high costs, powder metallurgy techniques such as additive manufacturing (AM) represent an economical approach to fabricating titanium components. Various approaches to AM, along with examples of components made by different AM processes, are presented. The microstructures and mechanical properties of Ti-6Al-4V produced by AM are also discussed and compared with cast and wrought products. Finally, the economic advantages of AM compared to conventional processing are presented.

For parts made by direct metal laser melting, heat treatment is important to set the final microstructure, which impacts mechanical properties.

Fabrication of aerospace components using additive manufacturing (AM) has matured to the point where part microstructures and mechanical properties compare well with those of conventionally produced material. This article looks at characteristics of AM methods, post-processing of AM parts, and AM part properties.

A joint Canadian venture launches a new facility with an innovative hybrid approach to cold spray additive manufacturing. The technology platform combines multiple manufacturing steps in a single cold spray additive manufacturing (CSAM) unit, incorporating surface preparation, cold spray forming and buildup, local laser-based thermal treatment, and in-situ sequential robotic machining and semi-finishing.
