Available in PDF, EPUB and Kindle. Book excerpt: To meet the challenge of transporting mineral and energy resources from the Canadian North as well as the need to conserve materials and energy, many new high-strength low-alloy (HSLA) steels have been and are being developed. This paper presents the results of the effect of low-temperature environments on steels. Four Arctic HSLA steels, a dual-phase steel, three experimental HSLA weathering steels and three experimental boron-HSLA steels have been used in the study. Tension tests have been carried out from room temperature to -196°C (-321°F) to evaluate the formability parameters (mainly uniform elongation and strain hardening exponent). Instrumented impact tests have also been carried out on the dual-phase steel to study its ductility under high rates of deformation. The relevance of this study to formability practice (in situ as well as "shop") of HSLA steels are pointed up. The areas where further work is needed are also discussed.

This book was released on 2014-06-13 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. To support the latest automotive challenges in terms of weight reduction, this book lays out the opportunities for alternative material use in automobiles and offers the most up-to-date design guidance in efficient architectures that use AHSS. It simultaneously explores weight savings and resulting fuel economy advantages of a strategic usage of AHSS. Realistic comparisons with other alternative materials are made through detailed analyses. It also offers test cases that demonstrate how AHSS technology has developed. The focus of the text is on body and chassis structures and the sheet metal of which these systems are primarily made. More of the content addresses the automotive body, as this is where most of the AHSS are being applied today. The past, present, and future of AHSS are covered, as well as competing technologies such as aluminum sheet metal.

Download or read book Formability Characterization of a New Generation High Strength Steels written by and published by . This book was released on 2003 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced high strength steels (AHSS) are being progressively explored by the automotive industry all around the world for cost-effective solutions to accomplish vehicle lightweighting, improve fuel economy, and consequently reduce greenhouse emissions. Because of their inherent high strength, attractive crash energy management properties, and good formability, the effective use of AHSS such as Duel Phase and TRIP (Transformation Induced Plasticity) steels, will significantly contribute to vehicle lightweighting and fuel economy. To further the application of these steels in automotive body and structural parts, a good knowledge and experience base must be developed regarding the press formability of these materials. This project provides data on relevant intrinsic mechanical behavior, splitting limits, and springback behavior of several lots of mild steel, conventional high strength steel (HSS), advanced high strength steel (AHSS) and ultra-high strength steel (UHSS), supplied by the member companies of the Automotive Applications Committee (AAC) of the American Iron and Steel Institute (AISI). Two lots of TRIP600, which were supplied by ThyssenKrupp Stahl, were also included in the study. Since sheet metal forming encompasses a very diverse range of forming processes and deformation modes, a number of simulative tests were used to characterize the forming behavior of these steel grades. In general, it was found that formability, as determined by the different tests, decreased with increased tensile strength. Consistant with previous findings, the formability of TRIP600 was found to be exceptionally good for its tensile strength.
Download or read book New Advanced High Strength Steels written by Mohamed Goune and published by John Wiley & Sons. This book was released on 2023-12-08 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, significant developments have been made to increase the mechanical strength of steels in order to reduce the overall weight of structures, particularly in motor vehicles. Depending on the application, the increase in strength should not be at the expense of forming and in-use properties. The development of ultra-high strength steels requires a search for new trade-offs between these properties in order to optimize the final microstructure. New Advanced High Strength Steels analyzes the interactions between tensile mechanical properties and properties such as work hardening, anisotropy, resistance to rupture, fatigue life, corrosion resistance, crashworthiness, edge retention, hydrogen resistance and weldability. It also examines the links between the microstructural parameters of high-strength steels and the properties mentioned above. It highlights the metallurgical developments that have been necessary for the emergence of these new generations of steels. The book concludes with a look ahead to future developments in ultra-high strength steels

This book was released on 1978 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variations in the strain hardening behavior of GM 980X and a vanadium-strengthened SAE 980X steel were investigated as a function of strain. Changes in the microstructural deformation characteristics of the two steels were evaluated by scanning electron microscopy after biaxial and uniaxial deformation. Plastic deformation was found to occur in the SAE 980X steel by deformation of the ferrite matrix, while in GM 980X it occurred by deformation of both the ferrite and martensite phases. The GM 980X ferrite matrix was found to have a much higher work-hardening rate than that of the SAE 980X steel. Failure occurred in the SAE 980X steel when the ferrite was highly strained. In GM 980X it occurred after more extensive deformation had occurred, and the martensite phase was also highly strained. It was concluded that the higher work-hardening coefficient of the ferrite matrix and the deformable martensite phase combine to give GM 980X its superior formability.
