U traženju odgovara na to važno pitanje radi velik broj istraživača u Europi i svijetu uključenim dominantno u projekte Eurofuzijskog konzorcija i Eurotama. U Laboratoriju za AC susceptibilnost Instituta za fiziku sudjelujemo u dva takva H2020 projekta (WPMAT i M4F). Razvili smo mjerne uređaje za mjerenje magnetske AC susceptibilnosti visoke osjetljivosti u visoko-temperaturnom području (zasad do 900 K). U kombinaciji sa mjerenjima susceptibilnosti u vremenskoj domeni (Magnetic After-effect) rezultati naših istraživanja pomažu razumijevanju fundamentalne fizike bcc-željeza na nanoskali, a osobito razumijevanju migracije defekata koja presudno određuje mehanička svojstva materijala. Usredotočujući se na migracije atoma ugljika (prvo u elementarnom čistom α-željezu a potom u tehnološki važnim legurama Fe-Cr) postepeno razvijamo metodologiju za detekciju i praćenje pokožaja atoma ugljika u ovisnosti o toplinskoj povijesti uzorka i izloženosti zračenju (zasad ionima Fe). Odgovor na pitanje gdje se točno nalazi ugljik: u itersticijskim položajima bcc rešetke, u precipitatima mnoštva mogućih karbida, granicama zrna, klasterima ugljik-vakancija, fizičkoj površini uzorka... presudan je za potpuno razumijevanje i projektiranje svojstava novih superiornih čelika. Naša dosadašnja istraživanja i metodologija temeljena na mjerenje magnetskih fenomena u velikoj mjeri daju odgovor na ovo pitanje. </span></p><p style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt;" data-mce-style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt;"></p><p style="color: rgb(0, 0, 0); font-family: "times new roman", "new york", times, serif; font-size: 12pt; margin: 0px;" data-mce-style="color: #000000; font-family: 'times new roman', 'new york', times, serif; font-size: 12pt; margin: 0px;"><b style="font-size: 12pt;" data-mce-style="font-size: 12pt;"><span lang="EN-GB" style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt;" data-mce-style="font-size: 11pt;"> </span></b></span></b><span style="font-family: arial, helvetica, sans-serif;" data-mce-style="font-family: arial, helvetica, sans-serif;"></span></p></div><div style="color: rgb(0, 0, 0); font-family: arial, helvetica, sans-serif; font-size: 12pt; text-align: left;" data-mce-style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 12pt; text-align: left;"><b><span lang="EN-GB" style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;" data-mce-style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;"> </span></b></span></b><b><span lang="EN-GB" style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;" data-mce-style="font-size: 12pt; font-family: 'Century Gothic',sans-serif;"><b><span lang="EN-GB" style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;" data-mce-style="font-size: 11pt; font-family: 'Century Gothic',sans-serif;">Voditelji seminara IF-a: <a href="mailto:hrvoje@ifs.hr" target="_blank">Hrvoje Skenderović</a> i <a href="mailto:damirs@ifs.hr" target="_blank">Damir Starešinić</a></span></b></span></b></div></div></div></div><br></div></div></body></html>
