Reinforcement architectures and thermal fatigue in diamond particle-reinforced aluminum

Determination of Internal Stresses in Lightweight Metal Matrix Composites

“…AlSi7/CD/60p behaves similar to AlSi7/SiC/60p with hydrostatic compression up to ~ -120±20 MPa closing the voids during heating, going into to ~ 120±20 MPa tensile stress at RT in which the voids reopen again. In Al/CD/60p, without eutectic Si connecting the diamond particles, low micro stress amplitudes were observed (Schöbel et al, 2010) together with an increase in void volume fraction during heating and decrease during cooling owing to the capability of the matrix to expand in a composite with isolated particles only touching each other. a) b) c) Fig.…”

“…11 a). In this MMC, with an AlSi7 matrix, the SiC particles are interconnected by eutectic Si bridges (Schöbel et al, 2010). These bridges result in the formation of an ICM with a 3D Si-SiC network embedded in the α-Al matrix.…”

Neutrons for industry

“…Thermal fatigue damage propagation is reduced by creating the interpenetrated composite network. In summary these interpenetrating networks are superior in heat management when compared to particles mixed into a pure Al matrix [66].…”

Experimental Simulation of Thermally Induced Stresses during Cooling of Continuously Cast Steel Slabs

“…[18,19] The first case represents the lower boundary of calculated result and the second in the upper boundary, both in respect to the Poisson's contribution in transverse direction of the Satoh test. [12] For the relative changes to be emphasized in first place to show stress evolution during cooling, the simple Hook's approach was chosen for calculation.…”
