Abstract
The structure and microstructure of impact fracture specimens of the heat-affected zone (HAZ) of low carbon micro-alloyed high-strength pipe steel welded joints are investigated. Correlation of structure parameters and fractographic characteristics of the failure micro-mechanism channel is established, providing information about elementary acts of failure, i.e., the dimensions of ductile and brittle microcracks.
