Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Y4Ni0.71Ag1.29: Expanding the Boundaries of the Gd4RhIn Structure Type

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
A first representative of the Gd4RhIn type with three transition metals. The new ternary compound Y4Ni0.71Ag1.29 has been prepared by arc melting the elements under inert atmosphere. Subsequent annealing at 800°C for 2 weeks yielded crystals of sufficient quality for structure determination by single‐crystal X‐ray diffraction.

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

Unveiling Ca9N4Te3: A New Motif in Alkaline‐Earth Metal Chalcogenide Nitrides: A Combined Experimental and Computational Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The unique double monocapped trigonal cupola coordination polyhedra of Te(2) atoms inside the crystal structure of Ca9N4Te3. Green, moisture‐sensitive Ca9N4Te3 was obtained from Ca/Na flux at 1173 K as a by‐product of reddish‐brown Ca6N2Te3 and crystallizes in the trigonal space group R3¯$\overline{3}$ (No. 148, Z = 3).
