1 Introduction During the past decades, the global requirements for a notable reduction of CO2 emissions due to energy-efficient transportation solutions have generated the development of several advanced high-strength steel (AHSS) types with high mechanical properties and good formability.[1, 2] Steel chemistries with a low-alloying element content are often favored in these kinds of steel because the aforementioned material qualities should be achieved at a relatively low cost.[1, 2]...

1 Introduction Stringent demands for reducing the carbon emissions from automobiles have led to the development of advanced high-strength steel (AHSS) grades; novel AHSS offers high strength-to-weight ratio at the same time maintaining cost efficiency.[1] The third generation of AHSS includes carbide-free bainitic steels, medium-manganese grades, and quench and partition (Q&P) steels.[2] Q&P is a heat-treatment process proposed by Speer et al.[3, 4] which involves complete or partial...

1 Introduction The current global need for more energy-efficient transportation solutions has generated extensive research work in the academic community and the steel industry. It has aimed at developing novel, advanced high-strength steels (AHSS) with high strength and excellent formability properties. However, the premature cracking during stretch flanging processes of AHSS has hindered their implementation in the automotive industry.
