Research ArticleOpen accessIn the keywordsCyclic Instability of Shape-Memory Alloys in Seismic Isolation SystemsFilipe Amarante dos Santos, Corneliu Cismasiu, Francisco Braz FernandesShape-memory alloys are being progressively introduced as kernel components in seismic retrofitting devices for civil engineering structures. In order to control the instability associated with the first mechanical cycles, a training procedure is usually implemented, which stabilizes the superelastic behavior of the alloy. This paper addresses the characterization of the cyclic behavior of an austenitic NiTi alloy with emphasis on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 7 Jan 2018 · 6,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,599 accessesView PDF Cite
