Tin–zinc-based alloys are under intense consideration as alternative lead-free solders for consumer electronics and telecommunications. This is because of their excellent creep resistance and fatigue resistance as well as mechanical and tensile pro

Amorphous Fe78Sn5B17 ribbons were prepared by planar flow casting. The thermodynamic stability and the kinetics of observed phase transformations were monitored by thermal analysis. The structure and morphology of phases forming upon the thermally ac

Previous works have shown that Nb protects Finemet (Fe73.5Si13.5B9Nb3Cu1) against oxidation. Still, the material must be annealed in a controlled atmosphere to induce nanocrystallization, otherwise, the oxide layer that is formed, deteriorates the so

The oxidation behavior of gas-atomized Al and Al alloy powder green compacts during heating prior to hot extrusion compaction was studied at laboratory and industrial scales by TGA, DSC, DTA, EDX, TEM and XRD methods. The effect of the heating of gre

Silica gel with extremely small pores of 3 nm diameter was filled with liquid cetane. Samples with various coefficients of filling k of cetane were prepared. After the solidification of confined cetane, its free volume has been investigated. The posi

The U-phase in the Al72Pd12.8Co15.2alloy was studied under non-equilibrium (casting, differential thermal analysis) and near-equilibrium (long-term annealing) conditions to consider its compositional homogeneity. In the investigation, scanning electr

The solidification/melting of cetane confined in nine silica glasses with specific controlled pores (CPG) with different pore sizes (r p ranging from 3.7–72 nm) has been studied. Samples with variable coefficient of filling of cetane were prepared

The rapidly solidified AlCr4.7Fe1.1Si0.3 (at.%) alloy produced at large scale by direct extrusion of gas atomised powders was investigated. Hot-extrusion yielded sound compacts and did not create any major structural changes compared to the as-atomis
