Mechanism of crack initiation and early growth of high fga1 steel equivalent to 25cr2ni11co15mo1 steel

Jan 13, 2020 · For the stainless steel, an initial crack is at first prefabricated on a notched specimen shown in Fig. 2b by variable stress amplitude fatigue test at the stress ratio R=1. Then, the notch is grounded by grade 1500 abrasive paper, and compressive fatigue test with 5 × 10 6 cyclic loading cycles is performed on the pre-cracked specimen. The maximum stress is 0 MPa and the minimum stress is fga1 steel equivalent to 25cr2ni11co15mo1 steel

A two-parameter model to predict fatigue life of high fga1 steel equivalent to 25cr2ni11co15mo1 steel

In this paper, ultrasonic (20 kHz) fatigue tests were performed on specimens of a high-strength steel in very high cycle fatigue (VHCF) regime. Experimental results showed that for most tested specimens failed in a VHCF regime, a fatigue crack originated from the interior of specimen with a fish-eye pattern, which contained a fine granular area (FGA) centered by an inclusion as the crack origin.
