<p>The method comprises introducing a thin-walled metallic component into a pressure-stable and liquid-tight container, filling off a remaining cavity of the component with a liquid medium such as water or hydrated liquid up to a predetermined height within the container, which has an increase in volume during transition of the liquid into solid aggregation state, and cooling the medium and/or cooling the container up to freezing the medium using liquid nitrogen in a shock-like manner. The solidification and compression of the component are carried out through the volume expansion of the medium. The method comprises introducing a thin-walled metallic component into a pressure-stable and liquid-tight container, filling off a remaining cavity of the component with a liquid medium such as water or hydrated liquid up to a predetermined height within the container, which has an increase in volume during transition of the liquid into solid aggregation state, and cooling the medium and/or cooling the container up to freezing the medium using liquid nitrogen in a shock-like manner. The solidification and compression of the component are carried out through the volume expansion of the medium during freezing. A cooling device is integratedly formed in the container. The process steps are repeatedly carried out. After each process cycle, the solidified medium is transferred again into the liquid aggregate condition by a heat supply. The container has several partial chambers for receiving a number of components. An independent claim is included for a component.</p> |
