Effect of fabrication methods on microstructure and mechanical properties of Fe3Al-based alloys

Tribological properties of self-lubricating NiAl/Mo-based composites containing AgVO3 nanowires

“…Furthermore, the disappearance of metallic Mo phase and the appearance of Mo 2 C precipitates in NAM and NAMV composites can be attributed to the high temperature solid-state reaction of metallic Mo and carbon. Carbon element comes from the methanol during MA process (added to the mixture powder during milling) or the graphite mould during sintering and holding process, which is consistent with the study of Jian Wang and A. Albiter [36,37]. The microstructure of NAMV composite is further characterized by SEM, as shown in Fig.…”

Characterization of Low-Symmetry Structures from Phase Equilibrium of Fe-Al System—Microstructures and Mechanical Properties

“…However, for the quantitative assessment of these parameters, it is necessary to know the basic parameter characteristic for each type of material, namely, the Young’s modulus. The value of this parameter was determined by the nano-indentation Vickers indenter, assuming a constant Poisson’s ratio at the level of ν = 0.3 [ 29 , 50 , 51 , 52 , 53 ]. In this method, the value of the Young’s modulus is defined as the value of the slope of the tangent to the force recorded during the unloading the indenter ( Figure 9 ) [ 30 , 48 , 49 ].…”

“…The observation of the micro areas in the corners most likely indicates the Palmqvist cracks which are characteristic for ceramic materials or cermets i.e. , Si 3 N 4 , B 4 C, WC-Co, ZrO 2 [ 53 , 54 , 55 ]. They are visible in the case of the FeAl 2 , FeAl 3 , and Fe 2 Al 5 phases in the range of a load equal to 500 g ( Figure 9 a,c,f).…”

B2+L21 ordering in Co2MnAl Heusler alloy

“…The profile analysis has a goodness of fitting factor (R p ) of 2.62% indicating the good agreement of experimental and theoretical profiles. Long range ordering parameter (LRO) is calculated by using the equation as reported in [3] and is 0.75. Hysteresis loops were taken at three different temperatures of 15, 30 and 50 K after field cooling the sample by applying a small field of 45Oe.…”
