Abstract During the manufacturing of cast aluminum (Al) engine blocks with iron (Fe) cylinder liners, the mismatch of thermal expansion/contraction coefficients between the Al cylinder wall and the Fe liners results in the development of high residual strains/stresses. This evolution of residual stress can surpass the strength of the currently used alloys and can lead to the premature failure of the engine block. Thus, improving the mechanical properties of the engine block alloys reduces the nu...

The growing demand for increased power output and efficiency of automobiles has led to the recent effort of improving the high-temperature properties of the currently used powertrain alloys. Research into the effects of rare earth additions, such as cerium (Ce), to aluminum (Al) alloys has been gaining momentum due its high-temperature stability associated with its unique Ce-bearing intermetallics. In this study, scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction and...

Abstract The effect of cerium (Ce) addition (0.1, 0.3, 0.5, and 1.0 wt%) on the ambient and high-temperature mechanical properties of a commercially available B319 powertrain aluminum alloy was investigated. In addition, to characterize the effects that Ce has on the microstructure of the B319 alloy, field emission scanning electron microscopy, optical microscopy, X-ray diffraction, energy dispersive X-ray spectroscopy and X-ray micro computed tomography were employed. Statistical significance o...
