Improving the mechanical properties of Mg alloys is great significance for their wide application. A micro-alloyed Mg-1.45Bi-0.79Ca alloy (in wt.%) exhibiting a high tensile yield strength 394 ± 5 MPa and moderate elongation 6.6 0.6% was fabricated by single pass extrusion. The superior mainly attributed to synergy effects ultra-fine dynamic recrystallized grains; numerous Mg2Ca, Mg3Bi2, Mg2Bi2...

Dilute Pd-in-Au alloy catalysts are promising materials for selective hydrogenation catalysis. Extensive surface science studies have contributed mechanistic insight on the energetic aspect of hydrogen dissociation, migration, and recombination dilute systems. Yet, translating these fundamental concepts to kinetics free energy dissociation nanoparticle operating at ambient pressures temperature...

2014 Measurements of magnetic susceptibility and spontaneous magnetization on face centred cubic platinum-iron alloys having compositions around Pt3Fe and also on alloys with lower iron contents, are reported. In the Pt3Fe superlattice region the alloys appear to be antiferromagnetic when ordered and ferromagnetic when disordered. The more dilute alloys are ferromagnetic, even down to 2 at. % o...
