Precipitation‐Modulated Harmonic Architectures Enable Superior Strength–Ductility Synergy from Cryogenic to Elevated Temperatures in Nanostructured Alloys

Advanced Science, EarlyView.
Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Liquid metal embrittlement during FAST joining of magnesium and galvanized steel

Journal of Magnesium and Alloys
Joining magnesium (Mg) alloys to steel is difficult due to metallurgical incompatibility. Applying a zinc (Zn) coating to steel enables formation of a thin Mg-Zn eutectic phase layer during welding, which promotes strong bonding.

On the Embrittlement of Mild Steel in Liquid Metals

Journal of the Society of Materials Science, Japan, 1969
The tensile test of unnotched and round specimens in the liquid tin, lead, zinc and bismuth bath was carried out with an Instron type testing machine in order to investigate the susceptibility of a mild steel to liquid metal embrittlement for which some inconsistent results had been reported among investigators.
