Redistribution of Residual Stresses During Fatiguestress domain at the surface not only retards the crack initiation but beneficially influences the crack propagation as well and therefore the effect of near surface stress conditions are much better understood.

Low Cycle Fatigue of Nitrogen Alloyed Martensitic Stainless Steels Si on crack initiation is discussed. It is pointed out that soft phase like “ferrite” in conventional 12%Cr martensitic steel could be a way to combine both high mechanical properties and good cyclic plasticity.

A Study of Fatigue Damage Using the Electrical Potential Methodes were interpreted to be the result of creep cavity initiation and growth. It is concluded that concurrent electrical potential measurement is a valuable tool in the study of damage in time-dependent, low-cycle fatigue.

Thermo-Mechanical Fatigue of Metal Matrix Compositesatigue damage. The failure of 20% silicon carbide particulate reinforced Al 2xxx-T4 under thermo-mechanical fatigue loading is dictated by creep-fatigue damages in the short-life regime and by oxidation damage in the long-life regime.

The Low Cycle Fatigue Behaviour of Titanium Alloysn a strong effect of test atmosphere (air, saltwater) on crack initiation and growth behavior was observed. At relatively low load amplitudes and with no surface damage, cracking took place internally. Typical crack initiation sites are quasi-cleavage facets which originate mainly at globular primary-α-phase.

Elasto-plastic behaviour of in 718 containing the δ-Ni3Cb precipitation phasese material differ from the properties of the same phase, which occures as precipitation phase in a two-phase material. The second phases’ properties will be obtained by an approach with try and error. With this data modelling by FEM will be useful to forecast materials behavior versus size, shape and distribution of a second phase.

The Influence of Mechanical Prehistory on the Cyclic Stress-Strain Response and Microstructure of Siquently cyclically loaded at various constant plastic strain amplitudes. The results are reported and compared with the cyclic deformation behaviour of specimens without predeformation. Differences in the stress—strain response are interpreted in terms of the microstructure observed by transmission electron microscopy.
