Advanced high strength steel (AHSS) development through chemical patterning of austenite

Scripta Materialia, 2018
Abstract A new approach for the development of medium Mn AHSS is proposed in this work. It exploits a fine scale (~ 100 nm) chemical patterning of Mn in austenite that may be obtained by the austenitisation of a pearlite structure formed under conditions with strong Mn partitioning between ferrite and cementite. The resulting ‘ghost pearlite’ ferrite/

Mechanical and Metallographic Effects of Laser Hardening of Two AHSS Steels

Materials Performance and Characterization, 2016
Abstract The search for suitable materials for the transport industry, to meet more stringent regulations related to crashworthiness, emissions, and fuel economy led to the development of advanced high-strength steels (AHSS). Thermal treatments, for example, using lasers as a process tool, can locally improve some characteristics of ...

CO2 laser cutting of advanced high strength steels (AHSS)

Applied Surface Science, 2005
Abstract This article demonstrates the optimum working areas and cutting conditions for the laser cutting of a series of advanced high strength steels (AHSS). The parameters that most influence the cutting of sheet metal have been studied and the results have been divided into two large groups with thickness of more and less than 1 mm. The influence

Springback Behavior of Advanced High Strength Steel (AHSS) CP800

Advanced Materials Research, 2013
800MPa grade Advanced High Strength Steels (AHSS), Complex Phase steel CP800, containing microalloying elements, are chosen to test the stamping properties in different test conditions and compared with traditional high strength low alloy (HSLA) steels HSLA S700MC. Tensile test, and HAT shape stamping test are taken to investigate the properties of the
