Metallurgia And Metal Forming

The pressing of sheet metal into useful shapes is a technology which requires an understanding of a wide range of subjects. This text is divided into three sections: processes, materials and tests. In Part 1, sheet metal forming is examined mainly from a mechanical engineering viewpoint; firstly plasticity and anisotropy, then process variables - friction, lubrication and temperature - and finally practical aspects of forming in the press-shop. Part 2 deals with the main sheet alloys at varying lengths, depending on their industrial popularity. Certain research results, showing the fallibility of the phenomenological approach, are also highlighted. A section of testing procedures concludes the volume.

Covers the basics of metal fabrication processes, including primary mill fabrication, casting, bulk deformation, forming, machining, heat treatment, finishing and coating, and powder metallurgy.

Micro Metal Forming, i. e. forming of parts and features with dimensions below 1 mm, is a young area of research in the wide field of metal forming technologies, expanding the limits for applying metal forming towards micro technology. The essential challenges arise from the reduced geometrical size and the increased lot size. In order to enable potential users to apply micro metal forming in production, information about the following topics are given: tribological behavior: friction between tool and work piece as well as tool wear mechanical behavior: strength and formability of the work piece material, durability of the work pieces size effects: basic description of effects occurring due to the fact, that the quantitative relation between different features changes with decreasing size process windows and limits for forming processes tool making methods numerical modeling of processes and process chains quality assurance and metrology All topics are discussed with respect to the questions relevant to micro metal forming. The description comprises information from actual research and the young history of this technology branch to be used by students, scientists and engineers in industry who already have a background in metal forming and like to expand their knowledge towards miniaturization. tribological behavior: friction between tool and work piece as well as tool wear mechanical behavior: strength and formability of the work piece material, durability of the work pieces size effects: basic description of effects occurring due to the fact, that the quantitative relation between different features changes with decreasing size process windows and limits for forming processes tool making methods numerical modeling of processes and process chains quality assurance and metrology All topics are discussed with respect to the questions relevant to micro metal forming.

Reflecting hands-on experience of materials, equipment, tooling and processes used in the industry, this work provides up-to-date information on flat-rolled sheet metal products. It addresses the processing and forming of light-to-medium-gauge flat-rolled sheet metal, illustrating the versatility and myriad uses of this material.

This book helps the engineer understand the principles of metal forming and analyze forming problems--both the mechanics of forming processes and how the properties of metals interact with the processes. In this third edition, an entire chapter has been devoted to forming limit diagrams and various aspects of stamping and another on other sheet forming operations. Sheet testing is covered in a separate chapter. Coverage of sheet metal properties has been expanded. Interesting end-of-chapter notes have been added throughout, as well as references. More than 200 end-of-chapter problems are also included.
