“…Mathematical description of the damage is usually used as a damage parameter in a constitutive material model [7,9,11,12,20] or in a phenomenological method [10,24]. However, the determination of a damage parameter is a challenging subject.…”

“…With the requirements of frequent start-up und shut-down processes of power plants due to the flexibility of electrical power demand, in addition to creep and creep fatigue endurance, thermal mechanical fatigue cracking behavior has increasingly become an area of great interest (e.g. [6][7][8][9][10][11][12][13][14]). These investigations usually describe TMF life behavior independently of microstructural damage mechanisms.…”

“…Demands on thermal efficiency increase in power plant have been driving the development of ferritic and austenitic creep-resistant steels [1][2][3][4]. The superior combination of high creep resistance, high oxidation resistance, and lower thermal expansion coefficient makes P92 steel become the candidate material for thick wall components in power plants.…”

Microstructure characterization and impact toughness test were performed on the P92 steel weld metal which was sectioned from the component of the main steam pipe of an ultrasupercritical unit after 8000 h exposure at high temperature. Precipitates of M23C6, MX, and Laves phase were detected in the weld metal. The weld metal after long-term service possessed much lower impact toughness compared with the as-fabricated weld metal. Micro-cracks were also found in the weld metal which formed during the welding process. Impact toughness reduction in the weld metal was correlated with the microstructure evolution.

“….ully reversed axial fatigue tests were performed in [54] on smooth specimens of 18Cr2Mo ferritic stainless steel (type 444) at room temperature, 673 and 773 K in laboratory air, with the aim to investigate the effect of temperature on high cycle fatigue behavior. In [55] the experimental investigation involved three different steels. A commercial martensitic P92 steel was tested at elevated temperature as well as two martensitic steels, reinforced with either 0.007% of boron (VY2 steel) or 0.2% of titanium (Ti1 steel) to improve their long-term creep strength.…”

The work summarizes a large bulk of experimental data from specimens made of 40CrMoV13.9 steel. The first part of the paper deals with multiaxial fatigue strength of notched round bars tested under combined tension and torsion loading, both in-phase and out-of-phase. The results from multi-axial tests are discussed together with those obtained under pure tension and pure torsion loading from notched specimens with the same geometry. The second part of the paper summarizes data from uniaxial-tension stress-controlled fatigue tests on specimens made of the same steel. Tests are performed varying temperature, from room temperature up to 650°C. Altogether more than 180 new fatigue data are summarised in the present work, corresponding to more than two-years of testing programme. All fatigue data are presented first in terms of nominal stress amplitudes referred to the net area and then re-analysed in terms of the mean value of the strain energy density evaluated over a given, crescent shape volume embracing the stress concentration region. For the specific steel, the radius of the control volume is found to be independent of the loading mode
