Sažetak
An ultra high strength low alloy steel having the composition Fe-0, 25C-1, 4Cr-0, 8Mo-0, 3V-0, 1Nb (wt.%), has been developed using the electroslag refining process. In order to understand the failure behaviour of the material, tensile coupons, surface crack tension specimens, compact tension specimens, and pressure chambers were fabricated and tested. To select a suitable failure theory for this material, failure assessment has been carried out on pressure chambers and verified with test results. Fracture analysis has also been carried out on the cylindrical vessels containing axial surface cracks and it was found that failure pressure decreases with increasing in crack size.
