Review of warm forming of aluminum–magnesium alloys

Journal of Materials Processing Technology, 2008
Abstract Aluminum–magnesium (Al–Mg) alloys (5000 series) are desirable for the automotive industry due to their excellent high-strength to weight ratio, corrosion resistance, and weldability. However, the formability and the surface quality of the final product of these alloys are not good if processing is performed at room temperature.

Warm-forming practice

Journal of Mechanical Working Technology, 1978
Abstract This paper illustrates the manner in which the combined effects of stress and lubrication affect forming loads within the range of warm- and hot-working temperatures. Graphical results are presented showing how typical parameters such as billet flow stress, coefficient of friction of different commercially-used lubricants, punch pressure in ...

Warm forming die design, Part III: Design and validation of a warm forming die

Journal of Manufacturing Processes, 2015
Abstract Warm forming is a sheet metal stamping process at elevated temperature that can significantly expand the forming limits of light weight alloys such as aluminum. Most of the work detailed in the literature has been based on a laboratory setting with minimal guidance on how to design warm forming dies for high-volume production. The challenges

Warm Electrohydraulic Forming: A Novel High Speed Forming Process

Procedia Engineering, 2017
Abstract Electrohydraulic forming (EHF) is one of the high speed forming processes for sheet metals which has considerable effect on formability improvement. In this process, the electrical energy stored in a bank of capacitors, discharges between a pair of electrodes submerged in a fluid and forms the sheet metal.

Warm forming of stainless steel sheet

Archives of Civil and Mechanical Engineering, 2010
The aim of warm sheet metal forming processes is to improve plastic flow of material, as well as to decrease the springback effect. This investigation deals with the effect of temperature in the range from 20 °C to 700 °C on basic material parameters of stainless steel sheet metal such as yield stress, ultimate strength, total and uniform elongation ...
