In particular, immersion or direct quenching processes are widely adopted procedures in automotive and aerospace industries to minimize the formation of undesirable thermal and transformational gradients, which may lead to increased distortion and cracking. AVL FIRE® offers state-of-the art modeling functionality in the field of quenching. Various quenching approaches can be simulated; air quenching followed by spraying and finally direct quenching. Different numerical models cover physical specifics of the thermal treatment process, which significantly influences the properties of cast materials. Commonly investigated components are cylinder heads or engine blocks made of aluminum, which can, under certain circumstances, undergo exceedingly high operational loads leading to material failure. Cracks commonly appear as a consequence of downsizing and weight reduction. An everyday application thereof would be the weight reduction of passenger cars to minimize tailpipe emissions. Despite the complexity of the investigated problem and long physical times, short turnaround times offer a great platform for virtual prototyping.
