“…In AMCs, strengthening is often ascribed to direct and indirect strengthening effects -the direct being the contribution from load transfer from the matrix to the particles, and the indirect from the additional dislocations created during cooling on account of the difference in CTEs between the matrix and the reinforcement (Chawla and Shen, 2001). In the case of the Cu-18Zn-7Al-0.3Ni particles reinforced AMCs some additional factors could be advanced for the improved strength compared to that of the SiC reinforced AMC -the likely improved interface bonding between the particles and matrix, and the compressive type residual stresses reported to be asserted by SMA particles on the matrix on cooling (Lee and Taya, 2004;Kotresh et al, 2018). Metallic reinforcements are reported to offer better interface bonding to metallic matrices compared to ceramic particles (Selvakumar et al, 2017;Alaneme et al, 2019c).…”

“…This improved bonding results in enhanced interface strength, which allows for effective load transfer between the matrix and the particles (Huang et al, 2018). Furthermore, the compressive type residual stresses asserted by the particle on the matrix on cooling, is reported not to be relieved by heattreatment (Kotresh et al, 2018), and hence effective even when the composite is exposed to elevated temperatures. The corollary is that despite the relatively lower melting point of the Cu-18Zn-7Al-0.3Ni alloy compared to the refractory SiC, the SMA provides higher mechanical strength at temperatures within the hot working confines of the AMC, which is typical for most automobile engine working temperatures.…”

Se investigó el comportamiento del flujo de esfuerzo por compresión y las microestructuras de los compuestos de matriz de aleación de Al deformada en caliente (AMC) y reforzados con partículas de la aleación con memoria de forma (SMA) basadas en CuZnAlNi. La aleación base Al-Mg-Si reforzada con 4, 6 y 8% en peso de Cu-18Zn-7Al-0,3Ni, y 8% en peso de partículas de SiC, se obtuvieron mediante agitación doble y se sometieron a pruebas de compresión en caliente a una velocidad de deformación de 1,0 s−1, temperatura de 400 °C, y ~60% de deformación global constante, para ello se utilizó un simulador termo-mecánico Gleeble 3500. Las microestructuras iniciales y deformadas de los compuestos se examinaron utilizando microscopía óptica. El uso de partículas Cu-18Zn-7Al-0,3Ni como refuerzo dio como resultado el desarrollo de una estructura de matriz más fina en comparación con el SiC. La tensión de flujo y la dureza de los AMC reforzados con partículas de Cu-18Zn-7Al-0,3Ni fueron generalmente más altos que los de la aleación de Al no reforzada y la aleación de Al reforzada con SiC. También la tensión de flujo y, en gran medida, la dureza creció con el aumento en el porcentaje en peso de partículas de Cu-18Zn-7Al-0,3Ni en el AMC. La mejora observada con el uso de partículas de la aleación Cu-18Zn-7Al-0,3Ni se atribuyó a la combinación del refuerzo mejorado y el refinamiento del tamaño grano de la matriz, fortalecimiento la interface, el esfuerzo residual de compresión, la alta conductividad térmica, y la capacidad de amortiguación ofrecida por la aleación Cu-18Zn-7Al-0,3Ni.

“…The W/2024Al composite is a type of particle-reinforced aluminum matrix composite (PRAMC) used as a noble candidate for radiation shielding with desirable mechanical properties such as high strength, excellent corrosion resistance, and low density [1,2,3,4]. In the production process, the mechanical properties of PRAMC can be further improved by use of a high-temperature solution followed by rapid quenching and subsequent aging treatment [5,6].…”

W/2024Al composites can be used for radiation shielding with desirable mechanical properties such as high strength, excellent corrosion resistance, and low density. The quench-induced residual stresses in W/2024Al composites were studied by experimental measurements and numerical analysis using ABAQUS software. Due to the accurate calculation of heat transfer coefficients and the established constitutive equation for description of the variation of yield stress at elevated temperature with different strain rates, the prediction of residual stresses in as-quenched composite blocks achieved by finite element method (FEM) is reliable. Moreover, X-ray diffraction and crack-compliance method were carried out to measure the stresses that developed at the surface and interior of the composites to validate the simulation results. Quenching residual stresses of composite blocks were investigated by taking the influence of quenching medium temperature into consideration. In addition, a comparative study on residual stress magnitudes of as-quenched 2024Al and W/2024Al composites was conducted, and the results show that stress magnitudes of W/2024Al composites are lower than that of 2024Al due to lower thermal gradients during the quenching process.
