| Mechanical fatigue Microporosity | |
| The enhancement of the fatigue behavior of a widely Al-Si casting alloy (A356) by affecting solidification by pressure up to 20 atm was investigated. By applying pressures of 1, 10 and 20 atm during solidification, the formation of microporosity in castings was mitigated. This enhancement in the microstructure of the alloy, related with a lower porosity, gave a significant improvement of its fatigue behavior (5 x 106 cycles). The microstructure is determined by the cooling rate of the alloy affecting the secondary space arm (DAS), the Eutectic Silicon particles (morphology, size and distribution), and the porosity (morphology, maximum pore size, and distribution). Also the effect of the Strontium modification and the use of flux on the fatigue behavior of this aluminum alloy were investigated. | |
