The temperature a material must withstand and any requirements for heat transfer through it, are important considerations in its selection for an application. Thus, it would be expected that the thermal management in a vehicle would have far reaching effect on the materials to be used for the different automotive systems. With the need to have more power intensive engines, smaller under-the-hood space, and the need for strict emissions control, the temperatures encountered by most components of thermal management system, including engine body and internals, lubricating and trnasmission oil cooling systems, engine coolant cooling system, the exhaust system, and other numerous components under the hood, are steadily on the increase. An added need is to use lighter materials to reduce the total weight for less fuel consumption and reduced emissions to meet the ever-increasing CAFE ratings.

Connecting rods are crucial and highly stressed parts of the automotive engine, subjected to alternating tensile and compressive stresses. Large numbers of them are needed. Conventionally, they are made of ferrous alloys and are made by casting or drop forging. The final dimensions and finish are obtained by machining. With the need to reduce automobile weight, the engine also needs to be lighter, more power intensive, and with well balanced components. Lighter and well-balanced oscillating engine components like the connecting rods and pistons enable higher engine rpms, and lesser noise and vibrations. Often, the lighter materials with the requisite strength are costly, but lesser quantity of material may be needed because of more precise design and manufacturing possible with them. There may also be a reduction in manufacturing and finishing processes, reducing labor requirements, and also reducing the loss of the material as chips during finishing.

This book provides a methodology for integrating materials selection with the design process, including simultaneous technical and economic evaluation. Save hours of frustrating research time – this resource provides you with fast answers about the best material for particular applications. In the past, it was nearly impossible to research the endless sources on corrosion and materials, in their countless applications. That’s why this book was written: to help simplify your materials selection problems. Topics include corrosion-resistant materials, types of corrosion, factors affecting corrosion, passivation, corrosion monitoring, corrosion control measures, methodology of materials selection, and more.

The paper reviews the growth of the use of different non-ferrous metals and alloys in the automotive industry to meet the needs of weight reduction, high heat dissipation and high temperature strength and corrosion resistance. It examines the potential of growth of this use in the light of some recently developed non-ferrous materials and processing techniques which are finding growing applications in the aerospace industry. Since the automotive industry cannot afford the high costs to the same extent as can the aerospace industry, the use of some of the improved materials would need to keep pace with the growth of the cost benefits of their use in this industry.
