High pressure gas quenching is an established heat treatment process that has some obvious advantages compared to the use of liquid quenchants: a low impact on the environment, the possibility of a more direct control of the quenching results and reduced distortion. In this paper, concepts for the optimization of the high pressure gas quenching process of parts that are arranged in a load are presented. With the aid of numerical simulation, using different detailed levels of the process and experimental investigations in a model chamber as well as in industrial gas quenching facilities, guidelines are developed for a more uniform quenching. Here, two aspects of the process are covered: On one hand, the arrangement of the parts in the load and the interaction with the upstream flow profile and the flow distribution is analyzed. On the other hand, the possibilities of how to effectively control the local flow are shown e.g. by mounting nozzle systems inside the load for a locally focused and increased heat transfer from the parts. Using these nozzles, parts can also be quenched asymmetrically for compensation of their distortion potential. A heat transfer measurement technique for verification of the numerical results is introduced briefly.
