High Energy Rate Forming High energy rate forming is the forming of sheet metal by a high energy surge, delivered over a very short time. Since the forming of the metal occurs so quickly, desirable materials for (HERF) will be ductile at high deformation speeds.

Explosive Forming. Explosives can deliver a huge amount of power. Book: All Authors / Contributors: American Society for Metals. OCLC Number: Notes: Cover title. Description: 29 pages illustrations 28 cm: Contents: The Convair dynaforming concept of high energy release rate forming, by E.W.

Feddersen.-High energy rate metal forming. In some cases, electrical high energy rate forming (HERF), as it is called, enables shaping and forming operations to be carried out which would be impossible by other means.

Shapes can be produced in metal using either one or the other of two established processes — electromagnetic or electrohydraulic by: Advanced high energy rate forming. Detroit, ©(OCoLC) Document Type: Book: All Authors / Contributors: American Society of Tool and Manufacturing Engineers. OCLC Number: Notes: Technical papers presented at the ASTME Creative Manufacturing Seminars.

Description: volumes illustrations 28 cm. High Energy Rate Forming (HERF) Processes Introduction: The forming processes are affected by the rates of strain used. Effects of strain rates during forming: 1. The flow stress increases with strain rates 2.

The temperature of work is increases due to adiabatic heating. Improved lubrication if lubricating film is maintained. Size: KB. The following are three common High-Energy Rate Forming processes: Explosive Forming: In explosive forming, the metal sheet is clamped over an evacuated die and the whole assembly is kept in a tank confined within a fluid medium (e.g.

High energy rate metal forming. book. A shock wave in the fluid medium is generated by detonating an explosive charge placed at a certain distance from the workpiece in the. The second part is composed of seven chapters and covers fundamentals of mechanical working, forging, rolling, extrusion, drawing of flat strip, round bar, and tube, deep drawing, and high-energy rate forming.

The book comprises an exhaustive description of mechanical properties evaluated by testing of metals and metal working in sufficient. High Energy Rate Forging High energy rate forging, is a metal forging process in which the actual forging of the work occurs in a few thousandths of a second.

This type of manufacturing technique is very useful for hard to forge metals. UNIT 8: High Energy Rate Forming (HERF) Processes Introduction: The forming processes are affected by the rates of strain used.

Effects of strain rates during forming: 1. The flow stress increases with strain rates 2. The temperature of work is increases due to adiabatic heating. Improved lubrication if lubricating film is maintained.

cessing. Metal forming is the main method of making metal products and semi-finished products. More than 90% of smelt-ed metal is processed by different methods of metal forming.

Plastic properties of metals are used during the process of metal forming. That is the ability to change without damage the. High Energy Rate Forming, High Energy Rate Forming- by Dr.

HIGH ENERGY RATE FORMING PROCESS [HERF ] It is a process that form products at very high velocities and extremely high pressure 3. Our proprietary high-velocity forming and manufacturing technology is ideally suited for shaping thin metal with high precision.

Since pattern design and quality is directly related to a bipolar plate’s energy efficiency, this type of forming technology pushes the boundaries for what’s currently possible in terms of hydrogen fuel stack efficiency.

•Temperature in Metal Forming •Strain Rate Sensitivity •Forming and related operations performed on metal sheets, strips, and coils •High surface area-to-volume ratio of starting metal, •Higher total energy required (due to the thermal energy to heat the workpiece) •Work surface oxidation (scale), poorer surface finish.

This book has 18 chapters divided equally between the broad headings of metal forming and impact mechanics. The section on metal forming mechanics includes papers that explore an upper bound approach to metal forming processes; rotary forming of rings under kinematic constraints; and microcomputer programs for rolling and extrolling.

As the only comprehensive text focusing on metal shaping processes, which are still the most widely used processes in the manufacture of products and structures, Metal Shaping Processes carefully presents the fundamentals of metal shaping processes with their relevant applications.

The treatment of the subject matter is adequately descriptive for those unfamiliar with the various processes and 5/5(2). High Energy Hydro Forming is a metal forming process whereby high energy material is ignited under water. The resulting water wave pushes the blank into the male or female die.

The whole forming process takes place in approximately 2 milliseconds. Advantages of High Energy Hydro forming are: Forming of very large sizes possible i.e.

This book has earned the reputation as the most respected introduction to metal-forming technology i. Home. Property Search. Knovel offers following tools to help you find materials and properties data.

Material Property Search. The first edition of this book was published a decade ago; the Preface stated the objective in the following way. In this book, the theory of engineering plasticity is applied to the elements of common sheet metal forming processes.

Bending, stretching and drawing of simple shapes are analysed, as are certain processes for forming thin-walled. High-energy-rate metal-forming techniques, for fabrication of structural high-strength components for airframe and spacecraft sheet metal application are presented.

The forming techniques demonstrate that the controlled application of the energy available from high-velocity explosives is a safe, efficient, and economical production forming method.

High‑Energy‑Rate Forming (HERF) Processes to form metals using large amounts of energy over a very short time HERF processes include: Explosive forming Electrohydraulic forming Electromagnetic forming© John Wiley & Sons, Inc.
