This book was released on 2018-12-18 with total page 631 pages. Available in PDF, EPUB and Kindle. Book excerpt: The automotive industry requirements for vehicle weight reduction, weight containment, improved part functionality and passenger safety have resulted in the increased use of steel grades with a fully martensitic microstructure. These steel grades are essential to improve the anti-intrusion resistance of automotive body parts and the related passenger safety during car collisions. Standard advanced high strength steel (AHSS) grades are notoriously difficult to be formed by cold stamping; they are characterized by elastic springback, poor stretch flangeability and low hole expansion ratios. Hot stamping has therefore received much attention recently as an alternative technology to produce AHSS automotive parts.In this book, selected articles from the Fourth International Conference on Advanced High Strength Steel and Press Hardening held on August 20-22th, 2018 in Hefei, China, are compiled. It focuses on AHSS for the development of press hardening of high performance sheet metal for lightweight vehicle, advanced digital manufacturing technology, as well as the physical metallurgy principles of the hot stamping process.Aiming at the process design and industrial application for hot stamping of press hardened steel and high strength aluminium alloy sheet, the effect of temperature and strain rate on the formability and mechanical properties of the products is discussed. In addition, more practical cases are provided concerning accurate modelling and multi-physics coupling simulation of the hot stamping process. Furthermore, the influence of tool design on forming process, more precise process control strategies to increase production efficiency, and the improvement of hot stamping equipment by advanced design methods will also be presented.

This book was released on 2018-07-15 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is study on tool steel pacification and heat-treatment for all type of wear resistance steel and specially our D3 steel. Supported with value review. This research “theoretical and experimental” in Effect of Heat-treatment “hardening temperature, tempering temperature, and cooling rate“ in the Mechanical property “Hardness”, and Microstructure transformation on Tool Steel, all type of wear resistance steel, and specially D3 steel. The research study heat-treatment for two pieces of D3 die steel "Working at cone pulleys for nail manufacture" to modify there mechanical properties. The classification its type, properties and set on condition effect on it was discussed. Two set of experiments were done one to determine the effect of austenitization temperature and tempering temperature on the mechanical properties "hardness" and another "the basic one" to discuses improving its mechanical properties from view of microstructure transformations "type, amount, and properties" for each heat-treatment stage. This study was APPROVED as my BS graduate project from Metallurgy Engineering Collage, Cairo University 2001, and published after addition in experimental review at 2018.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Heat Treatment of Tool Steel: An Illustrated Description of the Physical Changes and Properties Induced in Tool Steel by Heating and Cooling Operations The following pages are intended to be helpful to the trained artisan and foreman, whose business it is to produce steel objects and tools for various purposes. Also to the merchant, manufacturer's representative, and other official, who frequently meet complaints which they would like to fathom, and are often called upon to assume a knowledge of the properties of steel somewhat out of proportion to the opportunities afforded by the daily routine of their business. In the steel trade, perhaps more than in any other trade, the consumer looks to the manufacturer to furnish instructions about all materials and processes relating to the properties of steel. This state of affairs arose quite naturally at a time when the means at our disposal for investigating and classifying tool steels were confined exclusively to an examination of the fractured ingot or bar. This kind of examination the steelmaker developed into an art, which he practised with wonderful proficiency and accuracy long before the science of analytical chemistry was competent to replace his "tempers" by percentages of carbon. From the combined experience of the maker and user of steel there arose eventually a system whereby material of approximately the same kind was supplied, from whatever source it came, for the same purpose. As this system was based on appearances intelligible only to the competent steelmaker, it was inevitable that he should, in most cases, become arbiter and judge as to defects and remedies incidental to the heat treatment of tools.

Download or read book Heat Treatment Selection and Application of Tool Steels written by William E. Bryson and published by Hanser Publications. This book was released on 2005 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a few short years, this has become the established reference for tool makers, heat treaters, and engineers seeking step-by-step recipes for properly heat treating a wide range of tool steels, plus practical information about machinability, shock resistance, wear, and extending tool life. Now, the completely revised and expanded Second Edition of the best selling Heat Treatment, Selection, and Application of Tool Steels is available. It has been extensively updated and includes the following significant new additions: an entirely new chapter on the popular powdered tool steel CPM 10V; a thorough new section on carburizing thoroughly describes the process and its benefits; the section on cryogenic treatment has been completely rewritten to describe the theory and process; and a comprehensive glossary of related terms has been added. As in the first edition, valuable tables of properties, attributed, qualities, and shortcomings of popular tool steels are also included.
