This paper presents a preliminary research about a newly developed glass-steel composite created with diffusion welding of glass (C49-1) and carbon steel (St3sp). The main conclusions on the process of forming a diffusion zone during the welding of glass and steel are made. The results of quasi-static and cyclic mechanical tests and corrosion investigations are presented and interpreted on the basis of the microstructure developed during diffusion welding and described in this article. Keywords: hardening of glass, diffusion welding, glass-steel composite material, tensile tests, cyclic tests, fatigue, corrosion, microstructurê lanek predstavlja uvodne raziskave novo razvitega kompozita steklo-jeklo, izdelanega z difuzijskim varjenjem stekla (C49-1) in ogljikovega jekla (St3sp). Postavljeni so glavni zaklju~ki o postopku nastajanja difuzijske cone med varjenjem stekla in jekla. Na osnovi razvoja mikrostrukture pri difuzijskem varjenju so predstavljeni in razlo`eni rezultati kvazi stati~nih, cikli~nih mehanskih in korozijskih preizkusov. Klju~ne
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
