Fusing aluminum in a multi-material lightweight vehicle is presented via studies on joining dissimilar materials, joining methods, and the performance of the joined materials. The use of aluminum offers a material that embodies properties to meet new standards as the automotive industry continues to pursue improvements in fuel efficiency and emissions. Aluminum’s strength, light weight, and corrosion resistance offers manufacturers a material alternative to steel and an additional material, which has long been known in the industry, to be employed in automotive construction. Topics of technical interest include: • Forming • Galvanic Corrosion • Welding, Fastening, Bonding • Maximizing Weight Benefits Production of strong, lightweight structures will contribute significantly to automobile manufacturers meeting mandated fuel economy standards, as well as customer preferences for utility, comfort, and safety.
In the second edition of this best-selling book, new information and references are integrated into chapters. Emphasis is still on processing, alloying, microstructure, deformation, fracture and properties of major steel types ranging from low-carbon sheet steels, pearlitic rail and wire steels, to quench and tempered medium- and high-carbon martensitic steels. Microstructural aspects of steelmaking, hardenability, tempering, surface hardening, and embrittlement phenomena are updated, and chapters on stainless and tool steels remain in the second edition. The work is intended to be tutorial and is an essential state-of-the-art reference for anyone that makes, uses, studies and designs with steel.
Advanced high-strength steels (AHSS) are a family of steels that are stronger than most steels and have better formability than today’s conventional high-strength steels. New U.S. safety and fuel economy regulations have intensified pressure on OEMs to reduce vehicle weight. These pressures are causing auto companies to rethink alternative material applications and to look for opportunities that steel offers. The purpose of this book is to provide information for engineers who are designing the next generation of lighter vehicles. The material in the book is presented to help them make informed decisions on what basic materials to use and how to optimize those materials to achieve cost-effective weight reduction. The emphasis is on steels in general and AHSS in particular. However, there is much information on comparisons of steel with alternative materials for different subsystems of the vehicle.
This book provides a fascinating glimpse into a vital material that we may take for granted today. Stainless steel, called “the miracle metal” and “the crowning achievement of metallurgy” by the prominent metallurgist Carl Zapffe, is a material marvel with an equally fascinating history of people, places, and technology. As stainless steel nears the 100th anniversary of its discovery, this book is a fitting perspective on a vital material of our modern life, and it is the first book that captures the unfolding excitement and innovations of stainless steel pioneers and entrepreneurs. Amply illustrated with photographs, the book also includes a timeline that lists more than 450 important facts and events related to stainless steels technology and applications.
Aimed at those responsible for the operation of fabrication shops and maintenance/repair facilities, this guide helps the non-welding engineer in the selection of method, materials, and procedures to produce the “desired results and stay out of trouble.” Chapters include: • The Questions (you need to ask) • Key Background Information • What Happens When You Weld • Selection of Proper Welding Filler Metal • Metallurgically-Related Weld Discontinuities (Defects) and Typical Causes • Weld Defects and Causes • Weld Examination and Testing • Postweld Treatments
The 2004 SAE Ferrous Materials Standards Manual provides a comprehensive compilation of the SAE Technical Reports relating to specifications, testing, and defining of Ferrous Materials. These standards, Recommended Practices, and Information Reports have been developed by Carbon and Alloy Steels Committee, Metals Test Procedures Committee, Automotive Iron and Steel Castings Committee, Sheet and Strip Steel Committee, Elevated Temperature Properties of Ferrous Metals Committee who comprise the Metals Technical Executive Committee (MTEC). MTEC also governs the other Standards, Recommended Practices, and Information Reports that have been developed by prior division that are now inactive. As an informational guide and background for the values and procedures in the SAE Technical Report, HS-30 also includes Examples of Related SAE Technical Papers.
