The object of the experimental studies was to determine the mechanical properties of a hypoeutectic EN AC - 42100 (EN ACAlSi7Mg0,3)

silumin alloy, where the said properties are changing as a result of subjecting the samples of different types to solution

treatment. An important aspect of the studies was the use type of device for the heat treatment. As a basic parameter representing the

mechanical properties, the tensile strength of the metal (Rm) was adopted.
