Abstract

Diffusion bonding of duplex stainless steel to medium carbon steel was carried out with different temperatures for sound bonds. in the bonding process, relatively intermediate temperatures such as 750, 800, 850 and 900 degrees C were used with a bonding time of 30 min. In this study, microstructural changes and mechanical properties in the interface region of duplex stainless steel and medium carbon steel couples were determined. The results showed that, in interface region, Cr(23)C(6) was formed on the stainless steel side, while ferrite formation was observed on the carbon steel side as a result of mutual diffusion of C and Cr.
