H13 (Tool steel 1.2344) is a tool steel grade standardised for hot working. The main feature of this grade is the combination of alloyed elements of chromium, molybdenum and vanadium, Cr-Mo-V, which provides a high wear resistance to thermal shock. It is well known as for its great strength, and heat resistance. It is heavily used for die casting and the cold heading field. The presence of high vanadium in DIN 1.2344 can handle the abrasion at both low and high temperatures. It always provides a uniform and high level of machinability. This tool steel is mostly used for aluminum, magnesium and zinc die casting.

SOLID-MAP: Development of a Materials Acceleration Platform for High-Entropy Alloys
Antikainen, A., Jokiaho, T., Kaunisto, K., Lambai, A., Laukkanen, A., ..., & Zeb, A.
In this paper, researchers present the application of SOLID-MAP for screening, fabricating, and characterizing new HEAs for specific applications with InssTek’s MX-Lab which can print multiple powders simultaneously.
Experiment
Target HEA compositions included Mn, Cr, Fe, Co, Al, and V. Printing of selected samples was performed with commercial DED machine(MX-Lab, InssTek).
And, applied automatic XRD measurements for phase analyses and SEM-imaging-based defect analyses for determining the quality of printing as function of processing parameters.
Conclusions
Researchers developed a streamline workflow in which real-world alloys are suggested by integrated computational materials engineering and their practicability was measured using various automated characterization.
Preliminary results show that SOLID-MAP approach can significantly speed up the development of new HEAs and reveal new insights into their behavior and potential.
