“…In addition, micro-cracks could be seen on quasi-cleavage planes. Such marks were reported by Wang et al [46,51] for the piston aluminum alloy, under cyclic loadings at 120-425°C. They indicated that at 280°C, brittle quasicleavage fractures of the aluminum matrix, with broken silicon platelets and other intermetallic particles, were observed at fracture surfaces.…”

In the presented article, the temperature effect was studied on creep properties and fracture behaviors of AlSi12Cu3Ni2MgFe aluminum-silicon alloys, unreinforced and reinforced with SiO2 nano-particles. For such objective, standard specimens were fabricated by gravity casting and stir-casting methods, for aluminum alloys and nano-composites, respectively. Then, force-controlled creep testing was performed on standard specimens at 250, 275 and 300°C, under 100 MPa. Then, to find failure mechanisms, the fracture surface of test samples was also analyzed by the field emission scanning electron microscopy. Experimental results depicted the temperature changed creep behaviors of both materials, effectively. Moreover, a significant improvement in creep properties was observed by reinforcing the aluminum matrix with nano-particles, besides a heat treatment process. Such an increase in the creep lifetime was higher at 300°C. In addition, the fracture surface investigation of both materials implied the same brittle behavior, with quasi-cleavage marks. The failure location changed from inside the intermetallic phase into boundaries of the intermetallic phase in the nano-composite.

“…Besides, continuous thermal cycle will result in expansion of Si particles and local microplasticity around the α-Al/Si interface accelerating the deformation of composites, the concept has also been reported in Ref. [22]. Therefore, in this study, the fracture modes of 4.5μmSiC p /Al-7Si composite are debonding and aggregation of SiC particles, along with the detachment of eutectic Si phase, while for 4.5μmSiC p /Al-13Si composite, the detachment of eutectic Si phase is the main fracture mode; meanwhile, the broken primary Si phases are very rare.…”

“…Sehitoglu [21] found that the TMF life of Al/SiC composites became longer with smaller SiC particle size. It was investigated by Wang et al that the TMF damage behavior of Al-Si piston alloy was affected by temperature ranges; the cracks mainly initiated from the broken primary silicon in the temperature range of 120~350°C and nucleated from the interface between matrix and primary Si in the temperature range of 120~425°C [22]. However, the effect of particle size and Si contents on the TMF behavior of spray-deposited SiC particles reinforced Al-Si alloy has rarely been investigated.…”

The thermomechanical fatigue (TMF) behaviors of spray-deposited SiCp-reinforced Al-Si alloy were investigated in terms of the size of Si particles and the Si content. Thermomechanical fatigue experiments were conducted in the temperature range of 150-400°C. The cyclic response behavior indicated that the continuous cyclic softening was exhibited for all materials, and the increase in SiC particles size and Si content aggravated the softening degree, which was attributed to dislocation generation due to differential thermal contraction at the Al matrix/Si phase interface or Al matrix/SiC particle interface. Meanwhile, the TMF life and stress amplitude of SiCp/Al-7Si composites were greater than those of Al-7Si alloy, and increased with the increasing SiC particle size, which was associated with “load sharing” of the direct strengthening mechanism. The stress amplitude of 4.5μmSiCp/Al-Si composite increased as the Si content increased; however, the influence of Si content on the TMF life was not so significant. The TMF failure mechanism revealed that the crack mainly initiated at the agglomeration of small-particulate SiC and the breakage of large-particulate SiC, and the broken primary Si and the exfoliated eutectic Si accelerated the crack propagation.

“…FEM piston thermal and mechanical analysis gives rise to an extensive number of studies [1][2][3][4][5][6][7][8][9]. Hence, many researchers studied this phenomenon focused on the FE analysis of strains/stresses by advanced numerical methods [10][11][12][13][14].…”

The piston material choice is a major factor in the design stages of internal combustion engines for its importance to improving the durability and the operation reliability during the piston life cycle. Indeed, even as many researches have been conducted for a long time to improve the piston performances in the diesel engine, considerable numbers of piston damages still significantly occur. This research work is an assessment by the finite element method (FEM) of a set of piston materials for the purpose of being used in a direct injection diesel engine. The main objective is to predict stresses concentrations and the clearance between the piston and the cylinder (to avoid metal-metal adhesion) from thermomechanical solicitations. The stresses and deformations are evaluated in a 3D piston model by using ABAQUS software. A first assessment step is performed in heat convection/conduction modes to determine the temperature distribution. Then, this last one is coupled to the pressure field resulting from the gas combustion in order to compute stresses and the magnitude displacement. The obtained results show that the austenitic steel AS12UNG with fibre-reinforced possess low thermomechanical stress values compared to other material types. This material allows a minimum failure risk and therefore contributes to the enhancement of the piston design.
