Evaluating the mechanical behavior of hot rolled Al/alumina composite strips using shear punch test

Influence of zirconium addition on the microstructure, thermodynamic stability, thermal stability and mechanical properties of mechanical alloyed spark plasma sintered (MA-SPS) FeCoCrNi high entropy alloy

“…The particle sizes were measured using Image J software. While the particles sizes variation was recorded to be in the range of 5 and 50 nm, the average particle size showed to be around 12 nm, which is close to the value obtained from the XRD peak broadening by the Scherrer equation (Table 2) [22]. The analysis of the SAED pattern (Figure 4 (b)) confirms the results obtained from the XRD analysis verifying the formation of FeCoCrNiZr 0.4 solid solution with crystalline size of about 12 nm (Figure 4(a)).…”

Effects of Friction Stir Process and Stabilization Heat Treatment on Tensile Characteristics and Punch-Shear Properties of AZ61 Alloy

“…3(b), showing that the friction stir processed causes the dissolution of γ-Mg 17 Al 12 , only few γ-Mg 17 Al 12 and Al-Mn phase form in AF specimen. The EDS analysis of the particles in the AH specimens, the particles are γ-Mg 17 Al 12 and Al-Mn phase in grain boundaries after stabilization heat-treatment as shown in Fig. 3(c).…”

“…It is noted that the second phase particles stay around the at fracture surface and the crack region is without the second phase particles. The amount of at surfaces is increased with increasing the punch-shear strength by increasing the amount of alumina particles in the aluminum matrix 12) . It is con rmed that the at surfaces is closely related with the texture and the second phase particles (Fig.…”

Advance on Al2O3Particulates Reinforced Aluminum Metal Matrix Composites (Al-MMCs) Manufactured by the Power Metallurgy(PM) Methods- Improved PM Techniques

“…Zabihi et al [16,17] had successfully produced the Al-MMCs strip with 2 wt% and 4 wt% Al 2 O 3 by PM techniques, in which the hot-rolling process was adopted, after the milling and vacuum hot pressing. The hot rolling process improved the uniform distribution of alumina particles in Al matrix and the bonding of Al and Al 2 O 3 .…”

“…However, the properties and the basic characteristics of composites are thought to be controlled by the mixing methods and sintering process. In the PM processes, the mixing process is the critical step towards a homogeneous distribution throughout the consolidated composite material [14][15][16]. The agglomeration and segregation of the particles undoubtedly deteriorate the mechanical properties of composites.…”
