Introduction Fracture is defined as the separation of a material into two or more parts under the influence of stress. Fracture in majority of the cases is initiated by a small crack which develops into a major separation to cause failure. It therefore becomes very important to study the influence of the crack on the structural integrity. Steel grade 14MoV6 3 is used for manufacturi g of boilers and steam pi elines designed for st m temperatur s up to 560°C. This paper presents t experimental analysis which included impact toughness test. The analysis resulte in impact energy values, and their resp ctive components, crack initiation and crack propagation energy, a d repres nt the initial stage of extensive res arch involving th b havior of 14MoV6 3 steel. The aim wa t determi e the effects of temperature (room vs. operated), as well as the effects of specimen orientation with regards to the rolling direction, on the impact toughness and the relation between its components. © 2020 The Authors.

Introduction Fracture is defined as the separation of a material into two or more parts under the influence of stress. Fracture in majority of the cases is initiated by a small crack which develops into a major separation to cause failure. It therefore becomes very important to study the influence of the crack on the structural integrity. Steel grade 14MoV6 3 is used for manufacturing of boilers and steam pipelines designed for steam temperatures up to 560°C. This paper presents the experimental analysis which included impact toughness test. The analysis resulted in impact energy values, and their respective components, crack initiation and crack propagation energy, and represents the initial stage of extensive research involving the behavior of 14MoV6 3 steel. The aim was to determine the effects of temperature (room vs. operated), as well as the effects of specimen orientation with regards to the rolling direction, on the impact toughness and the relation between its components.
