Gaur egun daukagun energia kontsumo sistemak erabateko aldaketaren beharra du faktore nabariengatik, batez ere suertatzen dituen ingurumen-arazoengatik, baina denboran zeharreko jasangarritasunagatik ere. Hori dela eta, ezinbestekoa da alternatibak aurkitzea hainbeste erabiltzen diren erregai fosilak ordezkatzeko. Testuinguru horretan, fusio‑energia nuklearra aurkezten da epe ertainera sortuko diren arazo asko konpon ditzakeen aukera teknologiko bezala. Artikuluan zehar, energia-iturri horren ezaugarri garrantzitsuenak azalduko dira, baita teknologiaren oinarri fisikoak ere. Horrez gain, teknologiak denboran zehar izandako garapena, gaur egungo ITER nazioarteko proiektuaren egoera eta horrek bilatzen dituen helburu nagusiak aurkeztuko dira. Azkenik, aurreko puntu guztiak kontuan hartuz, Bilboko Ingeniaritza Eskolan dagoen Fusio Materialen Laborategiaren aurkezpena egingo da, asetzen dituen beharrak azalduz bere eginkizuna ulertzeko asmoz eta instalazio desberdinen deskribapena garatuz.

“…In the steel, the hydrogen atoms diffuse to the regions of high tri-axial stress or some microstructural sites (e.g. inclusions, grain boundaries and vacancies) where they are trapped and reduce the ductility of carbon steel (Peñalva et al , 2012; Zhou et al , 2013; Lei et al , 2018). Despite of the high corrosion risk, carbon steel or low-alloy steel is still the cost-effective materials used for casing and tubing (Choi et al , 2011; Sun et al , 2018).…”

Purpose This paper aims to evaluate the sulfide stress cracking (SSC) resistance of L80 casing steels with different alloying chemistries (e.g. Ti-B and Mn-Cr-Mo) by correlating the reduction in area ratio with the mechanical property, inclusion and carbide. Design/methodology/approach SSC tests were conducted in 5.0 Wt.% sodium chloride and 0.5 Wt.% acetic acid solution saturated with H2S using constant load tensile method. The microstructure and fracture morphology of the steel were observed using scanning electron microscope. The inclusion and carbide were identified by energy dispersive spectroscopy and auger electron microscope. Findings Among all the testing steels, electric resistance welding (ERW) L80-0.5Mo steel demonstrates the highest SSC resistance because of its appropriate mechanical properties, uniform microstructure and low inclusion content. The SSC resistance of L80 steels generally decreases with the rising yield strength. The fracture mode of steel with low SSC resistance is jointly dominated by transgranular and intergranular cracking, whereas that with high SSC resistance is mainly transgranular cracking. SSC is more sensitive to inclusions than carbides because the cracks are easier to be initiated from the elongated inclusions and oversized oxide inclusions, especially the inclusion clusters. Unlike the elongated carbide, globular carbide in the steel can reduce the negative effect on the SSC resistance. Especially, a uniform microstructure with fine globular carbides favors a significant improvement in SSC resistance through precluding the cracking propagation. Originality/value The paper provides the new insights into the improvement in SSC resistance of L80 casing steel for its application in H2S environment through optimizing its alloying compositions and microstructure.
