“…22MnB5 steel is considered a suitable alternative to traditional high-strength low-alloy steels and other advanced high strength steels (AHSSs), as it offers superior mechanical properties, exceptional formability, while being relatively cost-effective for producing structural parts and components with tailored properties. The chemistries of various boron-alloyed press-hardened steels have been reported extensively in the literature [52][53][54][55][56][57][58][59][60], with the bulk composition of the 22MnB5 steel discussed in the manuscript given in table 1:…”

“…The Al-Si coating affects the hardness of the fusion zone (FZ) in the ARW and ARWHS conditions, with lower hardness observed when the Al-Si coating has not been removed prior to welding [12]. The as-received BM hardness in the literature has been measured to be around 250 HV, while the hot-stamped BM (HSBM) hardness has been measured to be around 500-550 HV [8,12,14,15,17,23,[55][56][57][74][75][76][77]. In the as-received condition, both the as-received BM (ARBM) and the ARW samples failed in the BM, since the FZ was fully martensitic in the ARW case [12].…”

The automotive industry is seeking reduced vehicle weight and improved safety of newer generation vehicles to meet global zero-emission targets. Tailor-welded blanks (TWBs) offer a solution to meet this demand by producing lightweight yet strong components, such as the B-pillar, using laser-welded press-hardened steels. The laser welding of Al-Si coated PHSs causes the coating to be diluted into the melt pool which can cause premature failure due to the presence of a softer ferrite phase in an otherwise martensitic joint. Currently, laser ablation is used to remove the Al-Si layer prior to welding, but other techniques have been proposed which can potentially bypass the need to remove the coating and instead, welding directly through the coating. This study examines the problem of fusion zone (FZ) softening during the laser welding of Al-Si coated 22MnB5 and discusses recently proposed novel solutions that can solve the issue without the prior removal of the Al-Si coating before welding or using expensive filler materials during welding. The paper concludes with several viable recommendations for future work that can be used as potential directions for further research.

“…examined the modification of the mechanical characteristics of 22MnB5 steel under the effect of magnetic pulses and induction heating during restoration. The acquired results were validated by measuring hardness and comparing it to the evolution of the characteristics during hot stamping processes [4].…”

Manufacturing components and parts for a specific application are generally fabricated by traditional methods followed by industrial standards. With the modern era of machining components new materials, composites and alloys have also been developed for particular applications having desirable and required properties. Boron steel is one such material being used in manufacturing industries for agricultural spades, knives, blades, etc. in its raw form. In the present work, boron steel's properties and chemical composition have been compared when it is heat treated. It was observed that the working life span has been increased effectively and efficiently. This has also been verified using ANSYS.
