IMS 2015: Microstructural Characterization of Aerospace Materials & Coatings, Extended Abstracts (May 11–14, 2015; Long Beach, California, USA
The Microstructural Characterization of Aerospace Materials and Coatings is an exciting area in which to work, study, and play, and we will continue to meet and bring inspired people together in forums like this, to ensure IMS remains at the cutting edge in our industries.
Final program, show directory, and tutorial presentations from the Aerospace Coatings conference held October 8-9, 2014 at the Sheraton Bradley Airport Hotel in Hartford, Connecticut, USA.
ISTFA 2014: Proceedings of the 40th International Symposium for Testing and Failure Analysis (November 9–13, 2014, Houston, Texas, USA)
"Exploring the Many Facets of Failure Analysis," is the theme of the 40th International Symposium for Testing and Failure Analysis (ISTFA 2014), November 9–13, 2014, at the George R. Brown Convention Center in Houston, Texas, USA.

Zinc coated steels for hot press forming are intended to offer active corrosion resistant ultrahigh strength steel for applications in the automotive industry. During hot-press forming, zinc can infiltrate the underlying grain boundaries during the heat and forming step, leading to intergranular cracking of the base metal.

Fish scale appearance on cold rolled two-side enameled steels has become a large issue within the modern industry. This paper attempts to outline a number of methods used to make the hotrolled steel more suitable for two-side enameling after being cold rolled.

Knowledge of the flow stress behavior is important in seamless pipe rolling due to a need for accurate estimation of the roll force in order to optimize rolling schedules and avoid processing failures. In the present work, the hot flow behavior of high strength tubular grades was simulated by means of single hit compression tests conducted at various sets of deformation temperature and strain rate to replicate the mandrel mill rolling operation.

Traditionally, ultrasonic testing (UT) has been used for crack and/or flaw detection in pipeline steels and welds; however, the work presented in this paper explores using this technique to characterize the microstructure of an L80 steel.

Toughness of high-strength line pipes with longitudinal seam produced by Electric Resistance Welding (EW) is of paramount importance. During production, impact properties of the EW line are improved by a localized Post-Weld Heat-Treatment (PWHT). The heat treatment is intended to refine the structure and remove brittle constituents of the Heat Affected Zone (HAZ).
