An examination of some aspects of warm forging production
International Journal of Machine Tool Design and Research, 1974Abstract The information presented in this paper is some results from a broad investigation into the warm forging process. A comparison of the properties of four different component shapes forged at 800°C, 1000°C and 1200°C is made. The effects of several lubricants on forging at 800°C are examined and experiences with various tool steels presented.

A study on die wear model of warm and hot forgings
Metals and Materials, 1998Factors influencing service lives of tools in warm and hot forging processes are wear, mechanical fatigue, plastic deformation and thermal fatigue, etc. Wear is the predominant factor for tool failure among these. To predict tool life by wear, Archard’s model where hardness is considered as constant or function of temperature is generally applied ...

Current level of development of warm forging technology
Journal of Materials Processing Technology, 1994Abstract Although being a relatively new process, warm forging has already gained a firm foothold among the forming processes used for manufacturing complex high-quality components. As compared with cold forging, warm forging shows higher efficiency when intermediate treatments can be eliminated.

Warm forging: new forming sequence for the manufacturing of long flat pieces
Production Engineering, 2008Warm forming of steel is an economic and ecologic alternative to the conventional hot forging technology. It offers several advantages like decreased energy input, reduced scale formation, better surface quality and closer tolerances. Warm forming is common for rotation symmetric parts but has not been applied for long flat pieces yet.
