1. 21. Standardization of Eddy Current Testing Calibration for Valve Spring Wire

   University essay from KTH/Industriell produktion

   Author : Annick Ingabire; Robin Olsson; [2018]
   Keywords : NDT; ECT; Steel wire; artificial defect; crack; Calibration; NDT; ECT; ståltråd; konstgjorda defekter; sprickor; kalibrering;

   Abstract : Elektromagnetisk provning (ECT) har blivit en av de mest använda metoderna för attkvalitetssäkra produkter där icke-destruktiv testning av material krävs. Vid provning av ståltrådinteragerar utrustningen med det testade materialet och upptäcker ytdefekter och, i vissomfattning, om strukturen skiljer sig från det kalibrerade provet.

3. 22. Case depth measurements on inductionhardened crankshafts by using ultrasonic backscattering method

   University essay from Uppsala universitet/Tillämpad materialvetenskap

   Author : Sebastian Sirén; [2017]
   Keywords : Ultrasonic; Non Destructive Testing; Case Depth; Volvo; Ultraljud; oförstörande provning; härddjup; Volvo;

   Abstract : Induction hardening is a complex process that requires regular verification of the case depth and the microstructure. Today this verification is done by destructive testing where a cross section is analysed. The case depth is measured by several Vickers hardness impressions and the microstructure is analysed by a light optic microscope. READ MORE

4. 23. Testing and evaluation of component made using electron beam melting and Alloy 718 powder

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Erik Nilsson; Daniel Johansson; [2017]
   Keywords : Additive Manufacturing; AM; Electron Beam Melting; EBM; Alloy 718; Inconel 718; Inco 718; Non-Destructive Testing; NDT; Radiography; Computed Tomography; CT; Metallography; Additiv tillverkning; Oförstörande provning; Datortomografi; Röntgen; Metallografi;

   Abstract : The aerospace industry is constantly striving to becoming more economical and environmentally friendly. One of many efforts to achieve this is the Lightcam project which in this case is evaluating the use of additive manufacturing in the form of electron beam melting in conjunction with the nickel-based superalloy, Alloy 718.

5. 24. Bending properties of commercial wood-based panels by NDT methods

   University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

   Author : Francesco Poggi; [2017]
   Keywords : Wood-based panels; Non-destructive testing; Bending properties; Resonance vibration; Time-of-flight; Modulus of elasticity; Modulus of rupture; Stress wave velocity; Relative humidity.;

   Abstract : This thesis work focuses mainly on the application of non-destructive testing (NDT) methods on wood-based panels (WBP) in order to estimate the bending properties. To prove the accuracy and applicability of these methods on WBP, their results are correlated with results from a standardized static bending test. READ MORE

6. 25. Non-destructive testing of thin strip material : Implementation of the 3MA technique at a steel producing company

   University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Author : Jon Mikel Lizarralde; [2017]
   Keywords : Non-destructive testing; 3MA; steel strip; process monitoring and control; energy efficiency; sustainability; hardness; tensile strength;

   Abstract : This study is an initial attempt to investigate the possibility of substituting conventional laboratory destructive testing techniques at Sandvik's strip steel production facilities with the 3MA (Micro-magnetic Multi-parameter Microstructure and Stress Analysis) NDT (nondestructive testing) technique. The interest for the research comes from various problems with the actual destructive testing method. READ MORE
