Abstract
The 3xx series aluminium alloys are widely used for
automotive applications. However, increments in
engine power density result in higher alloy
mechanical properties requirements for components
such as cylinder heads. These alloys should perform
better at high temperatures (>200 °C). A good
alternative to the traditional Al-Si alloys are the Al-
Cu based alloys. However, hot tear tendency is a big
obstacle for the widespread use of this family of
alloys [1]. The present work focus on determine the
relationship between crack occurrence and grain
orientation, as a result of the solidification rate. Grain
refinement elements such as Ti and Zn are added to
the alloy to reduce hot tearing tendency. Two
different variants of AlCuMg alloy are evaluated at
different solidification rates.
