Thermomechanical fatigue (TMF) tests were carried out on a modified 9Cr-1Mo ferritic steel (P91) under a mechanical strain control mode using a strain amplitude of ±0.4% and a strain rate of 1.2×10−4 s−1. In-Phase (IP) and ...

Replacement of Mo and Nb by W and Ta in modified 9Cr-1Mo class of steels has been significantly useful for achieving reduced activity and improved mechanical properties. The addition of W and Ta strongly influences ...

Development of materials plays a crucial role in the economic feasibility of fast nuclear fission and fusion power plant. In order to meet this objective, one of the methods is to extend the fuel burnup and decreasing ...

Reduced Activation Ferritic-Martensitic (RAFM) steels are actively considered as structural material for blanket module of fusion reactor for its adequate creep rupture strength and better void swelling resistance than ...

Titanium bearing 14Cr-15Ni stainless steel is the material chosen for the fabrication of the fuel clad tubes used in the Prototype Fast Breeder Reactor which is under construction at Kalpakkam. The superior swelling ...

Creep tests on 316 L (N) stainless steel notched specimens with varying notch acuity were carried out and notch effect was studied. Various multiaxial stress states were generated by providing circumferential V-notch. The ...

The present work focuses on testing of 316 L (N) steel in which varying degrees of multiaxiality are introduced with variation in the stress intensity factor, Kt. The specimens were tested under varying notch geometries ...

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 ...

Creep rupture tests were conducted on plain and notched specimens of 316L(N) SS to assess the notch sensitivity of the material. The notched specimen contained a V-notch at an angle of 600 with root radius of 0.19 mm. The ...

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 ...
