Both B-H curve and magnetic DW behavior of high permeability grain oriented (HGO) electrical steel sample are measured and validated to be highly correlated with the applied tensile stresses by using a longitudinal Magneto-Optical Kerr Effect microscopy. Specially, the optical flow (OF) algorithm is used to track the DW motion, and the velocity of DW movement is verified to be decreased against the increase of tensile stress based on the OF velocity field. The variation of hysteresis loop is also closely related with change of speed of DW motion. This study provides detailed understanding on the relationship between macro and micro magnetic properties of HGO steel under tensile stress.","PeriodicalId":434318,"journal":{"name":"2015 IEEE Far East NDT New Technology & Application Forum (FENDT)","volume":"278 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134367114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The modified Hertzian theory was adopted for accurate theoretical analysis of the dynamic characteristics of the ultra-thin coating layer. Aluminum and Titanium thin films with 200 nm thickness were coated on the substrate using the DC Magnetron sputtering method. When the cantilever tip approaches and couples with a sample surface, the interaction forces and boundary conditions change in response to the sample contact stiffness. As a result, the contact resonance frequency of the vibrating cantilever shifts according to the local contact stiffness. This research demonstrates that Ultrasonic-AFM is a potential technique for nondestructively characterizing the mechanical properties of the ultra-thin coating layer.","PeriodicalId":434318,"journal":{"name":"2015 IEEE Far East NDT New Technology & Application Forum (FENDT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127427593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to inhomogeneity of testing materials and errors of detection systems, detected signals have phase errors, and distortion exists on synthesis images. This paper presents an effective phase correction method on ultrasonic synthetic focused signal distortion. A parameter, the relative signal-to-noise ratio, is introduced to be the indicator for later analysis. Via experimental results and the relative signal-to-noise ratios of the synthetic focusing images before and after phase correlation, the feasibility of the program is proved. Thus, the phase correction method here is worth putting the use into various ultrasonic application fields.","PeriodicalId":434318,"journal":{"name":"2015 IEEE Far East NDT New Technology & Application Forum (FENDT)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126473583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Flexible comb transducer, which can excite certain mode guided wave, can be used for the problem to complete the curved surface micro crack detection rapidly. But because of multiple modes when guided waves propagate in thin plate structure, the propagation law is complex. Considering controlling the excitation guided wave mode in such parts, we can obtain good detection effects. This paper carries out the guided wave mode control research in the process of excitation. We summarize the method to control the guided wave mode, and design the verification experiment by using fixed finger spacing comb transducer to excite the certain mode guided wave in the given thickness aluminum plate.","PeriodicalId":434318,"journal":{"name":"2015 IEEE Far East NDT New Technology & Application Forum (FENDT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129838933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed approach combines the advantages of both alternating current field measurement (ACFM) and eddy current pulsed thermography (ECPT) in physical level. It can produce relative uniform heating in surface and subsurface of ferromagnetic material and have an open-view for infrared imaging. The structure and physical mechanism of the ferrite-yoke based PIT are introduced. Numerical simulations are conducted to understand the general behavior and multi-physical interactions of the proposed method with stimulated magnetic flux, eddy current and induced heating in samples. Experiments are implemented to verify simulation results and identify the characteristics of the proposed method for characterization of the artificial and natural cracks. Results demonstrate the advantages of the proposed method on cracks quantitative evaluation in terms of combined magnetic flux and eddy current heating to defect orientations, uniform inductive stimulation and open-view for cracks visualization.
