Critical Factors Governing the Frictional Coefficient in Mg Alloys—Learn From Machine Learning

Engineering Reports, Volume 7, Issue 5, May 2025.
Machine learning models were successfully used to predict the friction coefficient of Mg alloys based on composition, processing, mechanical properties, and tribological parameters. Normal load, elastic modulus, and Zn content are the most important factors in governing the friction coefficient in Mg alloys. ABSTRACT Data‐driven methods are emerging as

Solidification of Tungsten Inert Gas–Welded Austenitic Stainless Steel with 0.17 wt% N

steel research international, Volume 96, Issue 5, May 2025.
The classical Scheil model with fast diffusion of nitrogen is used to describe the solidification of the weld seam from austenitic CrMnNi–N steel. The microsegregation of the elements Ni, Cr, Mn, Mo, and N is calculated and compared with experimental findings. Further, the correlation between secondary dendrite arm spacing and cooling rate is made.
