冷間壓延法에 依한 Aluminum Clad鋼의 接着機構에 關한 硏究 = A Study on Bonding Mechanism of Aluminum Clad Steel by Cold Rolling

다국어 초록 (Multilingual Abstract)

A number of studies on bonding mechanism of clad metals by cold rolling have been reported, but a definite conclusion of the bonding mechanism has not yet been recognized. In cold clad practice, it can be thought that the factors affecting the bondability may be kind of metals, surface condition, thickness ratio of metals, temperature, relative ship, and so on.
Several factors affecting the bond shear strengh of aluminium clad steel by cold rolling were examined. Furthere, the temperature of the bond during rolling was measured by I.C. thermo-couple. As the result, an average temperature of about 650℃ in 0.05 sec. was obtained.
From these facts it may be suggested that the bonding mechanism by cold rolling
is mutual fusion of metals at contact part under high pressure and high deformation by frictional heat caused by relative ship of metals.
