Failure Investigation of Hydrogen Blistering on Low-strength Carbon Steel
The current study assesses the root causes of hydrogen blisters on low strength carbon steel equipment. For this purpose, some experiments including hardness test, non-destructive test (NDT), metallography, and fractograpghy are conducted. The microstructure of two blisters is assessed by means of optical microscopy and scanning electron microscopy (SEM). The microstructural studies show that t...
متن کاملDevelopment of Hot-Rolled Sheet Steel with Significant Increase in Tensile Strength Induced by Strain Age Hardening*
A new type of bake-hardenable high strength hotrolled sheet steel was developed, which shows remarkable increase in tensile strength as well as yield strength after strain age hardening without addition of special elements. The new sheet steel possesses excellent crashworthiness and high fatigue strength, and also shows good formability almost equal to that of conventional high strength sheet s...
متن کاملStatistical discriminator of surface defects on hot rolled steel
A statistical approach to defect detection and discrimination has been applied to the case of hot rolled steel. The probability distribution of pixel intensities has been estimated from a small set of images without defects, and this distribution is used to select pixels with unlikely values as candidates for defects. Discrimination of true defects from random noise pixels is achieved by a dyna...
متن کاملStabilisation of ferrite in hot rolled d-TRIP steel
A steel has recently been designed to benefit from the deformation induced transformation of retained austenite present in association with bainitic ferrite. It has as its major microstructural component, dendrites of d-ferrite introduced during solidification. The d-ferrite replaces the allotriomorphic ferrite present in conventional alloys of this kind. The authors examine here the stability ...
