Correlation of Corrosion Resistance of Hot Rolled UHSS with Its Microstructure
Springer Proceedings in Materials, 2021Usage of Ultra High Strength Steel (UHSS) is found to be increasing in automobile application for enabling vehicle weight reduction with higher safety. This steel is mostly used for long and cross member of vehicle and exposed to contact of corrosive material while vehicle is running.

CO2 Laser Cutting Performance on Ultra High Strength Steel (UHSS)
Lasers in Manufacturing and Materials Processing, 2019 Evolution of a new breed steel, Ultra High Strength Steel (UHSS), has been adapted by the automotive industry after being used for heavy trucks. Higher tensile strength and improved mechanical properties of UHSS are the main reason for its selection particularly in Body In White (BIW) construction at critical chassis area.

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2014 In this research work, modeling of the hot flow behavior was carried out in a low carbon advanced ultra-high strength steels (A-UHSS) microalloyed with different amounts of boron (14, 33, 82, 126 and 214 ppm). For this purpose, experimental stress–strain

Journal of Materials Processing Technology, 2016 The usage of the hot stamping process is of great importance due to the high demands for production of ultra-high strength steels (UHSS). An Al-Si coating is normally applied to the steel to prevent decarburisation and scaling during heating and to ...

Microstructures and properties of uhss laser welds
ICALEO 2011: 30th International Congress on Laser Materials Processing, Laser Microprocessing and Nanomanufacturing, 2011Conventional welding processes often do not provide sufficient joins in high strength steels with multiphase microstructures. One of promising way is laser beam welding – working without filler metal, with sufficient capacity for automotive and transportation industry (where the amount of UHS steels increases each year as well as length of laser welds).

A Force Model for UHSS Hot-Formed Automobile Parts
Advanced Materials Research, 2014Combined numerical simulations and experimentally measured data, the relationship between the initial temperature of the workpiece was described, the stamping speed, and the required forming force. Air cooling was included to determine the temperature of the part within the mold, and the required stamping force was optimized by studying the impact of ...
