Abstract
The disclosure relates to a process for producing a hardened and tempered component made of specially heat-treated cast iron (e.g., AGI). According to the disclosure, a main body made of cast iron is prepared which may already be in the shape of an engine block. The main body may then be subjected to pre-machining, which may include forming one or more bores. Then, the main body may be hardened and tempered by a suitable heat treatment, such as a special heat treatment. After the disclosed heat treatment, post-processing of the component may follow, such as establishing the final dimensions.
