Bridging Experiment and Theory to Reveal Compounds in K–Zn(Cd)–Bi Systems
Zeitschrift für anorganische und allgemeine Chemie, Volume 651, Issue 10, July 7, 2025.Theoretically predicted compounds are experimentally realized via the facile hydride route, permitting experimental screening of K–Zn–Bi and “empty” K–Cd–Bi systems. The high‐yield synthesis has enabled a study of crystal and electronic structure, thermal stability, and magnetic properties of previously reported KZnBi, KZn2Bi2, and novel KCdBi and ...

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.
