Topotactic fluorination of intermetallics as an efficient route towards quantum materials

Nature Communications, 2022
Insertion of light elements in intermetallics has been explored to synthesize functional materials. Here the authors report topotactic intercalation of fluorine atoms into intermetallics using a perfluorocarbon reactant with covalent C-F bonds to obtain ...

The mechanism of Fe-rich intermetallic compound formation and growth on inoculants revealed by electron backscattered diffraction and X-ray imaging

Materials & Design, 2023
Fe-rich intermetallics affect critically the mechanical properties and recyclability of aluminium alloys. Increasing effort has been spent on the inoculation of these intermetallics, hoping to promote a finer distribution.

Internal friction in advanced Fe-Al intermetallics [PDF]

, 2006
We have measured the internal friction and the dynamic modulus of an Fe–38 at.% Al alloy using a forced torsion pendulum working between 10−3 and 10 Hz. The measurements have been carried out as a function of temperature (from room temperature to 1200 K)

Effect of Ce-base mischmetal addition on the microstructure and mechanical properties of hot-rolled ZK60 alloy

Journal of Magnesium and Alloys, 2021
Mg-Zn-Zr (ZK) alloys exhibit notably high mechanical strength amongst all magnesium alloy grades. However, due to the formation of low melting point Mg3Zn7-precipitates, these alloys are susceptible to hot cracking, thus compromising their metallurgical ...

Direct keyhole laser welding of aluminum alloy AA5754 to titanium alloy Ti6Al4V [PDF]

, 2014
The tensile strength of direct AA5754/Ti6Al4V joints performed by high speed Yb:YAG laser welding is found to be determined by morphology and phase content of dissimilar interface formed between contacting Al-rich and Ti-rich melted zones. Three types of
