Improving Forgings Formability by Warm Complexing Processes

Solid State Phenomena, 2017
Hand-tool is one of the important products which are widely used in manufacturing industry as well as in human life. The torx is one kind of hand-tools which is considered as a case study in this research. There are two trial preforms designed to analyze their influence on forgings formability.

A Study on the Warm Forging-Flaring Process of Brass Tube

Advanced Materials Research, 2014
At present, quite a lot of enterprises, small or medium-sized, are engaged in developing the various necessaries of livelihood. And, the forming processes are generally adopted for the methods of parts manufacture. Though various forming technology progress rather well, but the warm working process often cannot obtain fine finished products in the ...

A study on die wear model of warm and hot forgings

Metals and Materials, 1998
Factors 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 ...

Warm forging: new forming sequence for the manufacturing of long flat pieces

Production Engineering, 2008
Warm 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.

Current level of development of warm forging technology

Journal of Materials Processing Technology, 1994
Abstract 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.

Effect of vanadium in the warm forging of a medium carbon steel

1998
En el presente trabajo se analiza la influencia del vanadio en la microestructura y en la resistencia mecánica de un acero con contenido medio de carbono, tras ser deformado por compresión plana a temperaturas inferiores a 900°C. Los carbonitruros de vanadio no disueltos afinan la microestructura y junto a los reprecipitados durante el enfriamiento ...
