31. Fracture Toughness through a Welded Pipeline Section - Crack Tip Opening Angle Criterion
Topic: Metals
Published: 4/23/2007
Authors: Philippe P. Darcis, Christopher N McCowan, Elizabeth S Drexler, Joseph David McColskey, Avigdor Shtechman, Thomas A. (Thomas A.) Siewert
Abstract: The increasing demand for natural gas as an alternative energy source implies continued growth of gas pipeline installations. This trend compels the natural gas transmission industry to consider the construction of larger-diameter, higher-pressure pi ...

32. Analyzing Microstructure by Rietveld Refinement
Topic: Metals
Published: 6/1/2005
Authors: Davor Balzar, N C Popa
Abstract: Rietveld refinement has a primary purpose of refining crystal structure. However, this powerful technique is being increasingly used for obtaining microstructural information, such as texture, crystallite size, strain and stress, and crystalline defe ...

33. Residual stress determination by diffraction: Modeling and applications
Topic: Metals
Published: 1/1/2004
Authors: Davor Balzar, N C Popa
Abstract: Residual stress plays an important role in shaping Iilaterials properties. We present both the method to determine texture-weighted strain orientation distribution function for arbitrary crystal and sample symmetries and an example of the determinati ...

34. The NIST Charpy V-Notch Verification Program: Overview and Operating Procedures
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 1500-9
Topic: Metals
Published: 9/1/2003
Authors: Christopher N McCowan, Thomas A. (Thomas A.) Siewert, D P Vigliotti
Abstract: Charpy impact testing is often specified as ,in acceptance test for structural materials, and companies performing acceptance tests are typically required to verify the performance of their impact machine periodically. The procedure for verifying th ...

35. Intermetallics Formation and Growth at the Interface of Tin-Based Solder Alloys and Copper Substrates
Topic: Metals
Published: 2/17/2003
Authors: Juan C Madeni, S X Liu, Thomas A. (Thomas A.) Siewert
Abstract: Increasing concerns regarding environmental contamination is driving the soldering research community to develop lead-free solder alloys. Previous studies have shown that Sn-based alloys such as Sn-3.5Ag, Sn-0.7Cu, Sn-9Zn, and Sn-3.2Ag-O. ...

36. Application of an On-Line Weld Monitoring System
Topic: Metals
Published: 9/12/2002
Authors: Thomas A. (Thomas A.) Siewert, Ivan Samardzic, Stefanija Klaric
Abstract: quisition analysis and real-time manipulation of the welding parameters offer added controls over the weld quality. Thanks to the continual development of information technology and electronics, it is possible to improve the systems for monitoring ...

37. Estimation of Process Stability in the MAG Welding Process by Monitoring the Welding Parameters
Topic: Metals
Published: 11/1/2001
Author: Thomas A. (Thomas A.) Siewert
Abstract: This paper presents the distribution of the main welding parameters (welding voltage and welding current) for semiautomatic arc welding with the metal active gas (MAG) process, using both flux- cored and solid electrodes. Two different shielding fas ...
