High-quality nodule analysis in spheroidal graphite cast iron using X-ray micro-computed tomography

This work is a continuation of the studies presented in a recent paper by the authors, where a methodology to obtain different nodule quality categories in spheroidal graphite cast iron, was proposed. In this study, an exhaustive analysis…

Detection of Uniaxial Fatigue Stress under Magnetic Flux Leakage Signals using Morlet Wavelet

Syed Muhamad Firdaus, Azli Arifin, Shahrum Abdullah, Salvinder Singh Karam Singh, Noorsuhada Md Nor

This paper demonstrates the application of continuous wavelet transform technique for magnetic flux leakage signal generated during a uniaxial fatigue test. This is a consideration as the magnetic signal is weak and susceptible to being…

On the assessment of non-metallic inclusions by part 13 of API 579 -1/ASME FFS-1 2016

Jorge Luis González-Velázquez, Ehsan Entezari, Jerzy A. Szpunar

Improvement of nondestructive inspection techniques has allowed more frequent detection of closely spaced zones of non-metallic inclusions in pressure vessels made of low carbon steel. In the present study, closely spaced inclusions in an…
