Tribological Conditions in Hot Bending of 22MnB5 Tubes
2021Thanks to the high stiffness-to-weight ratio given by the closed-section geometry, tubular components are particularly suitable for automotive applications that require extreme lightness to reduce energy consumption and increase crashworthiness. Tube bending processes are traditionally performed in cold conditions, but to overcome the dramatic problems

Investigation of 22MnB5 formability in hot stamping operations
Journal of Materials Processing Technology, 2006Abstract In the automotive industry, the hot forming of high strength steels offers the possibility to obtain significant reduction of weight without affecting the structural performances of final products. The main reason of its restricted application in the industry lies however in the lack of basic knowledge about mechanical and microstructural ...

Microstructural analysis of hot press formed 22MnB5 steel
AIP Conference Proceedings, 2017This paper presents a microstructural study on hot press formed 22MnB5 steel for enhanced mechanical properties. Hot press forming process consists of simultaneous forming and quenching of heated blank. The 22MnB5 steel was processed at three different parameter settings: quenching time, water temperature and water flow rate. 22MnB5 was processed using

Experimental Study on Hot Bending of 22MnB5 Steel
Advanced Materials Research, 2011Special V-shaped heat bending test was designed for 22MnB5 hot forming steel of different thicknesses. Blanks after heating 5 min at around 950°C to austenize fully were bended at different temperature conditions, and simultaneously the spring-back behavior and microstructure features of heat bending specimens were investigated.

Basic Investigations on the Hot Stamping Steel 22MnB5
Advanced Materials Research, 2005Basic research concerning the material properties of the hot stamping steel 22MnB5 has been carried out. A survey is given about the as-delivered conditions with hardness tests, micrographs and flow curves. The process window of the austenitization time, before hot stamping can take place, is defined by austenitization tests.

Development of an Austenitization Kinetics Model for 22MnB5 Steel
Journal of Materials Engineering and Performance, 2018This paper presents a first-order austenitization kinetics model for 22MnB5 steel, commonly used in hot forming die quenching. Model parameters are derived from constant heating rate dilatometry measurements. Vickers hardness measurements made on coupons that were quenched at intermediate stages of the process were used to verify the model, and the Ac1
