Crystallization behavior and magnetic properties of Cu-containing Fe–Cr–Mo–Ga–P–C–B alloys
Multicomponent Fe65.5Cr4Mo4Ga4P12C5B5.5 amorphous alloy is known to have good soft magnetic properties combined with large glass-forming ability. Searching for a nanocrystalline structure that could improve its magnetic properties, Cr and Mo were partially substituted by Cu. The devitrification process of Cu-containing alloys shows an additional broad crystallization event that can be described...
متن کاملThe Effect of the Third Element Cr on Oxidation Behavior of Fe - x Cr - 10 Al ( at . % ) Alloys at 900 o C
Alloys Fe-(0, 5, 10)Cr-10Al (all in at.%) were oxidized at 900 o C in 1 atm oxygen to study the effect of Cr additions on the oxidation behavior. The oxidation kinetics was recorded with a thermal microbalance. The morphologies and microstructures of the oxide scales were examined using SEM, EDS, and XRD. Fe-10Al developed an Al2O3-rich scale during the initial stage of oxidation, and a non-pro...

متن کاملOxidation – Nitridation of Ni-Cr-Al Alloys
A series of alloys containing 24-36 wt pct Cr and 13.5 – 25.0 wt pct Al was reacted with air at 1100 °C for 260 h. The products of isothermal reaction were scales of α-Al 2 O 3 plus small amounts of Cr 2 O 3 . These grew according to parabolic kinetics, interrupted by episodic weight losses caused by partial spallation. No nitridation occurred during the isothermal exposures. Reaction during th...
متن کاملMultiple quasicrystal approximants with the same lattice parameters in Al-Cr-Fe-Si alloys
By means of atomic-resolution high-angle annular dark-field scanning transmission electron microscopy, we found three types of giant approximants of decagonal quasicrystal in Al-Cr-Fe-Si alloys, where each type contains several structural variants possessing the same lattice parameters but different crystal structures. The projected structures of these approximants along the pseudo-tenfold dire...
