Abstract

Eine Turbomaschine enthält ein Element, das aus einem Material ausgebildet ist, das einen ersten Wärmeausdehnungskoeffizienten aufweist. Das Element hat einen Riss (50). In dem Element ist ein Riss-Hemmsystem (70) vorgesehen. Das Riss-Hemmsystem (70) weist wenigstens ein Riss-Hemmelement (80) auf, das an dem Riss (50) vorgesehen ist. Das wenigstens eine Riss-Hemmelement (80) weist einen zweiten Wärmeausdehnungskoeffizienten auf, der sich von dem ersten Wärmeausdehnungskoeffizienten unterscheidet. Das wenigstens eine Riss-Hemmelement (80) ist eingerichtet und angeordnet, um eine Druckkraft auf das Element an dem Riss (50) auszuüben, um eine Rissausbreitung wesentlich zu hemmen.
