Quantification of ridging in ferritic stainless steel sheets by electron backscattered diffraction R-value maps.
In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sh...
متن کاملExperimental and numerical evaluation of electromagnetic acoustic transducer performance on steel materials
Electromagnetic Acoustic Transducers (EMATs) are an attractive alternative to standard piezoelectric probes in a number of applications thanks to their contactless nature. EMATs do not require any couplant liquid and are able to generate a wide range of wave-modes; however these positive features are partly counterbalanced by a relatively low signal-to-noise ratio and by the dependence of EMAT ...
متن کاملAccumulative Roll Bonding of Aluminum/Stainless Steel Sheets
An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...
متن کاملComparison of Defect Detection in Aluminum and Steel Plates Using an Electromagnetic Acoustic Transducer
Non-Destructive testing is useful in rail, pipeline and aerospace industries for maintenance of equipment, such as thickness measurements, corrosion and defect detection in materials. In this work a finite element analysis of an Electromagnetic acoustic transducer is presented. EMAT is an emerging technology that provides a non contact process of testing materials compared to ultrasonic sensors...
