ASM Handbook Volume 14B: Metalworking: Sheet Forming

This comprehensive reference on sheet metal forming and fabrication provides state-of-the-art reference information for product and production engineers. Coverage addresses all methods of sheet metal fabrication technologies, selection of equipment and die materials, specification of forming practices for specific alloys, and new techniques for process design and control.

This Volume provides you with practical reference information on the basic processes of press forming, drawing, bending, spinning, shearing, blanking, and piercing of sheet with additional coverage on forming with bar, tube, wire, shapes, or long parts. New content areas include :

Expanded coverage on computer-based methods for process simulation and control.
Advanced high-strength steels (AHSS) forming and material developments
Expanded coverage on the evaluation and mitigation of springback and the troubleshooting of formability problems
Rapid prototyping and die-less flexible manufacturing techniques such as thermal forming and peen forming 
Updates on cold-work powder metallurgy tool steels and tool coatings 
Updates and addition of practical reference information on basic operations of bending, press forming, and press brake forming

Application of tailor weld blanks 
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
