In the present paper, low cycle fatigue (LCF) behaviour of modified 9Cr-1Mo steel (P91 steel) and tungsten allo ed 9Cr steel (P92 steel) is presented. Total axial strain controlled fatigue tests were performed in air ...

Creep deformation and rupture behaviour of P92 steel has been examined at 923 K for stresses ranging from 75 to 150 MPa. The steel exhibited well defined primary, secondary characterized by minimum creep rate and prolonged ...

Creep-rupture properties of T91 steam generator (SG) tube steel have been examined at 923 K in normalised and tempered condition in the stress range 55-150 MPa. At all stress conditions, the creep deformation was characterised ...

The effect of nitrogen content on the dynamic strain ageing (DSA) behaviour of type 316LN austenitic stainless steel has been studied. The nitrogen content was varied from 0?07 to 0?22 wt%. The tensile tests were carried ...

In the present investigation, systematic studies on microstructure and mechanical properties of P92 steel subjected to various normalizing (1313e1353 K) and tempering (1013e1053 K) temperatures were carried out. The effect ...

Creep testing of notched cross-weld specimens was carried out at 873 K temperature and 300 MPa stress to study the effect of notch on creep properties of 316 L (N) SS weld joint. Various stress states were achieved by ...
