15.2.2 Damages due to Problems in Forged Parts and Powder-Metallurgical Parts
<a id="problems-of-forged-parts"></a>
Forged materials are still dominant today in parts under high cyclical stress, especially rotors (LCF) and compressor blades (HCF). The ever greater loads (centrifugal forces, thermal stress) demand reliably safe prevention of ever smaller flaws. <a id="flaws-in-forged-rotor-disks"></a><a id="solution-annealing-and-gamma-phase"></a><a id="disk-cracking-during-heat-treatment"></a…
