Paper presented at the Southern Metals Conference, American Society for Metals, in Atlanta on Apr. , The history and fundamentals of explosive forming of metals are discussed. The various types and forms of explosives available are described. The high explosives are more commonly used for explosive forming of metals than low explosives. Section 5: Forming Processes for Sheet, Strip and Plate Bending of Sheet Metal Press-Brake Forming Deep Drawing Stretch Forming Superplastic Sheet Forming Spinning Rubber-Pad Forming and Hydroforming Three-Roll Forming Contour Roll Forming High-Velocity Metal Forming Drop Hammer Forming Thermal Forming of Sheet and Plate Peen Forming Age Forming.

The scientific understanding of high-velocity deformation has advanced substantially during the past decade. On the one hand, the framework for a theory explaining the metallurgical effects of shock waves is beginning to take shape; on the other hand, the technological applications of high strain-rate processes have found their way into industries in countries around the world. Metalworking is the process of working with metals to create individual parts, assemblies, or large-scale structures. The term covers a wide range of work from large ships and bridges to precise engine parts and delicate therefore includes a correspondingly wide range of skills, processes, and tools.. Metalworking is a science, art, hobby, industry and trade.

Response of metals to high velocity deformation: proceedings of a technical conference, Estes Park, Colorado, July , Volume 9 of Metallurgical Society conferences Authors. Metal Forming Processes Paperback – by G. R. Nagpal (Author) out of 5 stars 5 ratings/5(5).

High-velocity forming of metals; a concise yet intensive treatment of the mechanics, principles, equipment and methods employed in the forming of metals by the explosive, electro-hydraulic, magnetic-pulse, and pneumatic-mechanical processes.

[American Society of Tool and Manufacturing Engineers.]. High-velocity metal forming was the focus of much research approximately 30 years ago.

It appears that this technology responds well to many of the challenges facing sheet metal forming today: formability is enhanced, springback is minimized, and die tryout time should be by: High - Velocity Forming of Metals Hardcover – January 1, by Frank W.

Effect of strain rate on forming process Higher the rate of strain hardening, lower is the recrystallization temperature. For mild steel, recrystallization temperature range may be taken as –°C.

Recrystallization temperature of low melting point metals like lead, zinc and tin, may be taken as room temperature. The effectsFile Size: KB. HIGH VELOCITY FORMING: High velocity metal forming was studied fairlyextensively between about to HVF or High velocity forming involves imparting a highkinetic energy to the work piece by accelerating it to ahighly velocity, before it is made to hit the appropriatedie These techniques include methods such asExplosive forming,Electro.

Electromagnetic forming (EM forming or magneforming) is a type of high velocity, cold forming process for electrically conductive metals, most commonly copper and workpiece is reshaped by high intensity pulsed magnetic fields that induce a current in the workpiece and a corresponding repulsive magnetic field, rapidly repelling portions of the workpiece.

In forming and in cutting, strain rates with values below 10 −1 s −1 based on the dynamic plastic behaviour of materials is categorised as slow process velocities. In superplastic forming (cf. Section ) strain rates are typically between 10 −5 s −1 and 10 −3 s −1.A strain rate between 10 −1 s −1 and 10 2 s −1 is defined as intermediate, while a strain rate of more than 10 Cited by: handbook of metal forming Download handbook of metal forming or read online books in PDF, EPUB, Tuebl, and Mobi Format.

Introduction In these forming processes large amount of energy is applied for a very short interval of time Many metals tend to deform more readily under extra – fast application of load which make these processes useful The parts are formed at a rapid rate, and thus called high – velocity forming processes.

These processes are useful to. Electrohydraulic forming is a high-velocity forming process that deforms sheet metals with velocities above m/s and strain rates more than s−1.

This experiment was conducted in a closed space because of safety concerns related to the high-velocity conditions; therefore, we were not able to examine the deformation process of the sheet : Min-A Woo, Young-Hoon Moon, Woo-Jin Song, Beom-Soo Kang, Jeong Kim.

High velocity deformation can be quite effective in increasing the forming limits of metal sheets as well as effectively treating some other common metal forming problems, such as wrinkling and distortion.

This study examines the high velocity formability of cold rolled sheet steel Cited by:. A constitutive model for rate-dependent and thermomechanically coupled plasticity at finite strains is presented.

The plasticity model is based on a J 2 model and rate-dependent behavior is included by use of a Perzyna-type formulation. Adiabatic heating effects are handled in a consistent way and not, as is a common assumption, through a constant conversion of the internal work rate into rate.New process related developments in superplastic forming and conventional forming of aluminum, titanium, nickel, magnesium, and refractory alloys; Recent process modifications in hydroforming and high-velocity metal forming.This practical and comprehensive reference gives the latest developments on the design of sheet forming operations, equipment, tooling, and process modeling.

Individual chapters cover all major sheet forming processes such as blanking, bending, deep drawing, and more. Process modeling using finite element analysis is described in one chapter and discussed in all appropriate chapters/5(3).
