Understanding the impact of the manufacturing defects (porosity, brittle inclusions) resulting from the Lost FoamCasting (LFC) process is a major concern in the cracks development under mechanical stress. The Al-7Si-3Cualloy (A319) will be considered in this crack mechanisms analysis. Generally, samples are obtained by cylinderhead sampling, but the variability in the distribution and characteristics of defects complicates the analysis ofcracking mechanisms. The new approach is to create a model test specimen with a representative cylinder headmicrostructure in terms of constituents and defects. Controlling the defect position allows to know the crack ini-tiation location. Hence, the observation area is limited during the mechanical test an...
