In order to improvethese features, new pre-hardened non-standard materials have been developed recently. The aim ofthe study is to characterize the fatigue behaviour of these new generation steels using the fracturemechanics approach: crack propagation thresholds as well as stable and unstable crack ...

The influence of various gasenous environments on fatigue crack propagation has been determined for three quenched and tempered steels with yield strength levels of 800 to 1400 MN/m 2 . The crack growth rate was increased by an order of magnitude in low pressure (13 KPa) hydrogen, and by a...

The present study deals with the fatigue crack propagation of two different precipitation hardened steels. The two steels differ in the nature of precipitate they bear. The steel having the soft precipitate with coarse grain and the steel having the hard precipitate with fine grain. Instead of ...

To clarify the mechanism of fatigue failure in eutectoid steel, fatigue crack initiation and propagation behaviors have been studied in detail under rotating bending fatigue tests using rail steels. The fatigue failure surface was also examined by using SEM. The main results obtained are as follows;...
The results showed that the rate of fatigue-crack propagation in the 18Ni (250) maraging steel was insensitive to moisture in the test environment. Nearly the same rates of crack propagation were observed in dry argon, humid argon, and humid hydrogen. The influence of dry hydrogen was, ...
