Magnetic Barkhausen emission to evaluate fatigue damage in a low carbon structural steel
TL;DR: In this paper, the various stages of fatigue damage in low carbon structural steel have been characterized using magnetic Barkhausen emission (MBE) signal analysis technique during high cycle fatiguing.

Non-linear ultrasonic technique to assess fatigue damage in structural steel
TL;DR: In this article, a non-linear ultrasonic technique has been used to assess the fatigue damage in low carbon structural steel and the percentage of total harmonic distortion, which is the ratio of the amplitude of 2nd harmonic and the fundamental, has been introduced as the measurement parameter in this paper.

Failure analysis of coal pulverizer mill shaft
TL;DR: In this paper, the failure of a ball and race type coal pulverizer mill shaft was investigated and it was found that the fatigue cracks originated from the keyway area, unusually from the top edge.

Influence of Saline Environment on creep rupture life of Nimonic-263 for marine turbine application
Sumanta Bagui,Ashok K Ray,Jitendra Kumar Sahu,N Parida,J. Swaminathan,M Tamilselvi,S. L. Mannan +6 more
TL;DR: In this article, the effect of Na 2 SO 4 and NaCl salt mixture on creep rupture properties of Nimonic-263 alloy at 800 and 850 degrees C was investigated and it was shown that for short duration tests, the rupture life is not much affected by the corrosive action of the salt mixture at both the temperatures.
