Pattern steel: production technology and fracture surface evaluation
Presented article deals with the description of the technology of pattern steel production – forging welding, evaluation of fracture surfaces and mechanical tests of examined samples (resulting steel and its individual components). The damascus steel (pattern steel) was prepared by forge welding from a packet consist of a few hundred layers. Marbling was created by folding layers of 2 components: hard and tough steel of different thickness. For evaluation of mechanical properties was applied: Charpy impact test. The evaluation of the fracture surfaces of individual samples was performed by scanning electron microscopy (SEM). The values of mechanical properties of pattern steel themselves are in the range of values of mechanical properties of individual components. The fracture surfaces of the materials have a characteristic relief (in relation to the mechanical properties of the individual components).
