Study of Phases Evolution in High-coercive MnAl Powders Obtained Through Short Milling Time of Gas-atomized Particles
(Elsevier, 2017)
Gas-atomized Mn54Al46 particles constituted nominally of only ε- and γ2-phases, i.e. no content of the ferromagnetic L10-type τ-phase, have been used to study the evolution of phases during short time of high-energy milling ...

Scratch, Fretting, and Sliding Wear of a ZrB2–hardened Zr3Al2 Intermetallic–ceramic Composite
(Elsevier, 2023)
The unlubricated wear behaviour of a very recently developed ZrB2–hardened Zr3Al2 intermetallic–ceramic composite was investigated for the first time. In particular, tribological tests of scratch, fretting, and sliding ...
