Friction and wear behaviour of tool steels sliding against 22MnB5 steel
Journal of Materials Research and Technology, 2017 Boron steels are used in hot stamping process due to their good mechanical properties. During the stamping process, the dies are exposed to aggressive conditions including adhesive wear, abrasion, thermal stresses and fatigue. In the present work, QRO 90

Microstructure Characterization of Reversed Transformation in Cryogenically Rolled 22MnB5. [PDF]
Materials (Basel), 2020 Hot stamping is a well-known process to produce structural automotive parts with an excellent strength-to-weight ratio. However, this process is more expensive due to the lower energy efficiency and operating cost of the traditional roller-hearth furnace.

Numerical modelling of the 22MnB5 formability at high temperature [PDF]
Procedia Manufacturing, 2019 Abstract It has been recognized in automotive sector that the use of hot stamped parts for the automobile body-in-white allows significant weight saving and reduction of CO2 emissions. The weight reduction is accompanied by high stiffness and increased crashworthiness, which improve the passengers’ safety and allow the development of more complex ...

Hőkezelt 22MNB5 acél kopásállóságának vizsgálata [PDF]
Műszaki Tudományos Közlemények, 2015 Az acélok ipari felhasználása napjainkban is jelentős. A gazdaságosság miatt azonban előtérbe kerülnek a nagyobb szilárdságot mutató, de alacsony ötvözöttségű acélok. Az általunk választott acél is ebbe a csoportba tartozik, hiszen meleg alakítással és gyors hűtéssel a szilárdsága jelentősen növelhető.

steel research international, Volume 94, Issue 11, November 2023., 2023 Herein, the effects of tempering temperature on microstructure, tensile behavior, and fracture properties under different stress states are investigated using the designed quenching and tempering medium‐Mn steel with ultrahigh tensile strength. The tempering temperature affects volume fraction and carbon content of retained austenite, which leads to ...

Advanced Engineering Materials, Volume 25, Issue 15, August 2023., 2023 The thermomechanically processed hat‐shaped profiles show high ductility and high strength properties simultaneously. A holding time of 30 s during forming and 10 s of transfer time allows for obtaining the highest‐graded properties. Coarse precipitates form in the grain interior and along the grain boundaries. η' strengthening precipitates and Guinier–

Oxygen‐Free Production—From Vision to Application
Advanced Engineering Materials, Volume 25, Issue 12, June 2023., 2023 Extremely low oxygen partial pressures can be obtained by adding small amounts of monosilane to an inert gas environment. The effects of such an environment on various production processes such as milling, compound casting, and thermal spraying are analyzed.
