dc.descriptionCracking in sour media modes were observed, and these were related mainly to the microstructure produced during the thermomechanical process of two microalloyed steels grade API X 52. Through the use of linear elastic fracture mechanics modified specimens. Steels loaded at similar initial stress intensity factors showed different cracking modes that were related directly to their different microstructures. Steels microstructures indicate different fabrication routes. Testing temperature played an important role on switching the cracking characteristics being remarkable by the ferrite-pearlite steel microstructure. A banded microstructure is susceptible to the effects of hydrogen at room T. While, an acicular ferrite microstructure with carbides patches at grain boundaries is susceptible to anodic dissolution in front of the crack tip, no matter the temperature being tested. Key words: microalloyed steels, sour service, cracking modes, microstructure. en-US

  • 2017: 6th Engineering, Science and Technology Conference - Panama (ESTEC 2017) [115]
    The 6th Engineering, Science and Technology Conference (ESTEC 2017) organized by the Universidad Tecnologica de Panama (UTP) is the most relevant conference, engineering-based, of our country. The topics of the conference are focused on areas of interest of Panama and the Latin America region, including: agroindustry, astronomy, bioengineering, education on engineering, energy and environment, ICT engineering, infrastructure and construction, logistics and transportation, manufacturing processes and material science, robotic, automation and artificial intelligence. This year, ESTEC partnered with IEEE Panama Section to ensure the quality of the peer-reviewed process; we received more than 180 full papers from 20 countries and 50% of those were accepted to participate in the conference and will be published in the conference’s proceeding. Furthermore, the conference included technical tours to the Cocoli’s Gate and the Miraflores Visitors Center of The Panama Canal and to the Wind Power Park in Penonome, Panama.
