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 Forming of Magnesium Sheet Metal

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">This paper deals with warm forming of Magnesium AZ 31 sheet metals. Experimental investigations on the formability of AZ31 at temperatures up 350°C have been carried out. The following the results of these investigations, such as stress-strain curves, forming limit curves are presented.

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 ...

Formability of AA6061 alloy sheets in warm forming temperature range

Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2019
Significant improvement in formability of aluminum alloys can be obtained when these materials are formed in the warm working temperature range (below recrystallization temperature).

Warm Forming of Mg Sheets: From Incremental to Electromagnetic Forming

Metallurgical and Materials Transactions A, 2014
Magnesium alloys are generating interest in the automotive and aeronautic industries due to their low density and potential to reduce gross vehicular weight. However, the formability of these alloys is poor and they are very difficult to be formed at room temperature due to their strong basal texture in rolled form.

Warm forming of aluminium/magnesium alloy sheet

Journal of Mechanical Working Technology, 1978
At this time, when energy conservation is gaining popularity, the increased use of aluminium sheets for motor-car body construction to reduce the overall weight of the car, and so use less fuel, is appropriate. Pure aluminium, as used in the days of hand-made bodies, is now quite out of the question for the mass-produced car, due to inherent softness ...

Incremental sheet forming of aluminum with warm

2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2015
This article aims to present a preliminary study of single point incremental sheet forming (SPIF) with warm for aluminum sheet of 1 millimeter (mm) thickness, with a propose of evaluate the contribution of adding heat for the process and even, how to reduce the processing time.

Alloyability of warm formed FeCrAl powder compacts

Materials Today Communications, 2015
Abstract Alloyability of warm formed Fe-based powder compacts is presented here. Iron (Fe) powder ASC100.29 was mixed with other alloying elements, namely chromium (Cr), and aluminum (Al) powder for 60 min and compacted at 150 °C by applying 130 kN axial loading, simultaneously from upper and lower punches to generate green compacts.

Warm forming of thermoplastic fibre metal laminates

Materials Research Proceedings, 2023
Abstract. In this paper, the forming behaviour of sheet-like metal/polymer/metal (MPM) and thermoplastic fibre metal laminates (TFMLs) is introduced. TFMLs are based on thin metallic cover sheets and fibre-reinforced thermoplastic matrix (here polyamide 6).
