Implication

Analysis shows that Aluminium 2618 reduces total deformation by 50% versus Aluminium 7075, indicating better material selection under thermal and mechanical loading.

Key Points

Aluminium 2618 reduced total deformation significantly compared to Aluminium 7075 and Titanium, improving mechanical performance.
The maximum heat flux was lowest in Aluminium 2618, underscoring its thermal advantages for engine pistons.
Analysis employed finite element methods to assess four piston materials under combined loading conditions.
These findings suggest Aluminium 2618 is more resilient under steady-state, though transient analyses are needed for final selection.
