Phased array ultrasonic imaging using angle beam virtual source full matrix capture-total focusing method
Sumana,Anish Kumar +1 more
TL;DR: In this article, an angle beam virtual source FMC (ABVSFMC) method is proposed to enhance the sensitivity by increasing the transmitted energy with specific directivity, which utilizes apertures of a few elements to obtain a diverging beam by focusing very near to the top surface (virtual source).
Journal Article
Characterisation of microstructure in 9 % chromium ferritic steels using ultrasonic measurements
TL;DR: In this article, the spectral peak ratio (SPR) was used for the assessment of grain size and identification of various metallurgical features affecting the grain size such as dissolution of carbides and formation of d-ferrite.
Journal ArticleDOI
Drilling of pultruded and liquid composite moulded glass/epoxy thick composites: Experimental and statistical investigation
TL;DR: In this paper, the best drill geometry and corresponding optimal process parameter levels for making defect tolerance holes in thick pultruded and liquid composite moulded (LCM) composites are revealed.
Journal ArticleDOI
Characterisation of long term aging behaviour of 9Cr-1Mo ferritic steel using ultrasonic velocity
TL;DR: In this article, the authors measured the ultrasonic velocity of 9Cr-1Mo ferritic steel thermally aged at 793 and 873 K and found that four distinct regimes in the variation of ultrasonic velocities with aging time were correlated with the progressive evolution and coarsening of precipitate microstructure.
Journal ArticleDOI
Evaluation of material degradation using phased array ultrasonic technique with full matrix capture
TL;DR: In this article, a new approach based on phased array ultrasonic technique (PAUT) with full matrix capture (FMC) is presented to effectively measure acoustic properties such as ultrasonic wave velocity and attenuation coefficient and to evaluate material degradation.
