I. Camagic et alii, Frattura ed Integrità Strutturale, 36 (2016) 1-7; DOI: 10.3221/IGF-ESIS.36.01 3 HAZ, both new and expoloited material, at room and service temperature. Only two diagrams are shown here, as an illustration, whereas the others can be found in [1]. 1.00E-10 1.00E-09 1.00E-08 1.00E-07 1.00E-06 1.00E-05 1 10 100 K, MPa m 1/2 da/dN, m/ciklus Figure 1 : Diagram da/dN-K for specimen PM-1-1n, 20°C. 1.00E-10 1.00E-09 1.00E-08 1.00E-07 1.00E-06 1.00E-05 1 10 100 K, MPa m 1/2 da/dN, m/ciklus Figure 2 : Diagram da/dN-K for specimen PM-2-1e, 540°C. Obtained values for parameters of Paris law, m d C K dN a , i.e. coefficient C and exponent m , fatigue threshold K th , and fatigue crack growth rate, da/dN , for K = 10 MPa m, are given in Tabs. 5-9 for new and exploited PM, for new WM, and for new and exloited HAZ, respectively.
