Investigation of friction in warm forging of AA6082

International Journal of Material Forming, 2008
This paper presents an experimental investigation of friction in hot forging of AA6082, which is a standard forging alloy in automotive engineering, mechanical engineering and in naval architecture, by employing a modified ring-on-disc test. The experiments were performed with three different commercial graphite-based lubricants and at various loads ...

Die life and lubrication in warm forging

Journal of Materials Processing Technology, 1997
Abstract Since the worm forging enables the processing of high strength parts with a high level of precision, it is possible to eliminate the cutting and grinding of the ball and roller grooves of the outer race of the constant velocity joints. The application of this process has been increasing each year and the size of parts made with the process ...

Some applications of cold and warm forging

Journal of Materials Processing Technology, 1992
Abstract Over the last few years, cold and warm forming of steel has gained greater importance. This is mainly due to one fact: there is an increasing demand for precision parts with high volumes especially in the automotive industry. Therefore, special manufacturing methods for special parts have been developed with warm and cold forging and with ...

Warm Forging of a Vanadium Microalloyed Steel

Materials Science Forum, 1998
An experimental study of the warm forging applied to a vanadium microalloyed steel has been performed by plane strain compression tests in the 720-870°C range, followed by air cooling and accelerated cooling (4°C/s). The microstructures obtained are ferrite-pearlite-bainite with very fine ferrite grain sizes.

Warm Forging Characteristics of AZ31 Alloy

Advanced Materials Research, 2007
Industrial application of magnesium alloys has increased significantly recently. However, wrought magnesium alloys still have a lot of technical challenges to be solved for more applications. First of all, low formability of wrought alloys should be improved by optimizing the processing variables.

Lubrication and Friction of Magnesium Alloys in Warm Forging

CIRP Annals, 2002
Abstract In order to realize precision forging of magnesium alloys, the frictional behavior of ZK60 (Mg–6%Zn–0.5%Zr) is studied. At room temperature, the friction test of ZK60 sliding over the surfaces of cemented carbide tool with and without TiC+TiCN+TiN and DLC (diamond like carbon) coating is carried out.

Warm forging of stainless steels

Journal of Mechanical Working Technology, 1982
Abstract The warm forging of stainless steels 1 Cr18Ni9Ti, Cr17Ni2, 2Cr13, 4Cr13 and Cr1 2Mn5Ni4Mo3Al has been studied. There are two problems to be overcome in the warm forging of stainless steels: the high resistance of these metals to deformation, and the pronounced tendency for metallic particles to adhere to the tools. The key factors leading to

Warm multiaxial forging of AISI 1016 steel

Materials & Design, 2010
Abstract In this work, the microstructural evolution in AISI 1016 steel processed by using warm multiaxial forging technique is studied. With increase in multiaxial forging strain, a finer substructure evolved. Structural evolution in pearlite phase is addressed in detail considering the strain paths and strain rate.
