“…It is evidenced by the change (increase) in the steel microhardness near the sides of the main crack, compared to the initial undeformed state. However, as noted by the authors of [41][42][43], the width of the plastically deformed region significantly decreases with the decreasing temperature.…”

“…In the works [41][42][43][44], the influence of impact test temperature both on the microhardness distribution along the main crack propagation path and the width of the plastic deformation region of the steel with a ferritic-martensitic microstructure was studied in detail. It has been shown [41][42][43] that the plastic zone is formed not only in the upper and central part of the temperature curve of the impact strength, but also on the lower shelf. It is evidenced by the change (increase) in the steel microhardness near the sides of the main crack, compared to the initial undeformed state.…”

“…Pipeline plates exhibit anisotropy of their mechanical properties due to their specific structural and textural states [5,[21][22][23][24]. Texture can affect steel strength and crack resistance in different ways, depending on the direction.…”

“…This splitting can be described as brittle cracks perpendicular to the main surface of the ductile fracture. They form in the vicinity of a propagating crack tip as a result of a triaxial stress state and due to the fact that under certain conditions a material can be ductile in one direction and brittle in another, thus exhibiting anisotropy of brittleness [23,24]. In [29], it was demonstrated that splitting does not have a significant influence on main crack propagation, i.e., they do not directly affect material fracture itself.…”

“…A intensidade das "separações" presentes na superfície fraturada dos corpos de prova do ensaio Charpy precisou ser caracterizada quantitativamente para permitir o estabelecimento de correlações com as variáveis do processo e condições de teste. Farber (2016) propôs um método trabalhoso envolvendo a medição das áreas afetadas por "separações" na superfície fraturada do corpo de prova de Charpy. No entanto, uma abordagem mais simples, proposta por Fernandes (2010), requer apenas a medição dos comprimentos das separações, uma vez que a relação comprimento/largura é praticamente constante.…”
