Ultrasonic assisted stir squeeze casting of AA5456/Al2O3–SiC-Gr-MoS2 hybrid nanocomposites: Microstructure and strengthening analysis
Published 2025-01-01“…Fractography analysis identifies various fracture modes, including ductile, brittle, and fatigue, along with their distinct surface features, providing insights into the fracture mechanisms of the AMMHNCs. The research also examines the primary strengthening mechanisms contributing to the increase in YS, including thermal mismatch, the Orowan effect, the Hall-Petch effect, and load bearing. …”

Crack of a helicopter main rotor actuator attachment: failure analysis and lessons learned
Published 2013-09-01“…Further achieved evidences, such as grain boundary fracture propagation, the presence of corrosion products, were all in accordance with a Stress Corrosion Cracking (SCC) progressive fracture mechanism. Finite Element Analysis (FEA) located the highest tensile stress value, when the servo actuator is in its nominal working condition, at the same points where the corrosion products were more concentrated (i.e. in the part of the fracture exposed to oxidative air effect for the longest time). …”
