Characterisation of the mechanical and corrosive properties of newly developed glass-steel composites

Abstract

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

Analytical Modeling for Segregation of Glass-Steel Composite Manufactured by Diffusion Welding

“…A composite of glass-steel was manufactured [24]: Glass C49-1 has the compositions of 67.5% SiO2, 20.3% B2O3, 3.5% Al2O, and 8.7% Na2O while carbon steel St3sp consists of 0.14~0.22% C, 0.15~0.30% Si, 0.4~0.65% Mn, 0.05% S, 0.04% P, 0.3% Cr, 0.3% Ni, 0.3% Cu, 0.08% As, and 0.01% N. The rod of the composite was heated from 20 C  to around 800 C  , then it was annealed to decrease the residual stresses. It is observed that grain size increases with the distance from the interface between the steel and glass.…”
