Testing of mechanical properties of products is one of the most important production stages because they, most objectively, allow determining whether products manufactured by a certain technological process meet the necessary requirements. Impact strength is the most important parameter in assessing the mechanical characteristics of tubular steel products, impact values …
Generalized temperature model of impact strength of low-alloyed steels subjected to hardening and high temperature tempering for +20 °С, -40 °С and -60 °С is received.

A method for separating the work of impact into two parts - the work of the crack nucleation and that of crack growth - which consists in testing two samples with the same stress concentrators and different cross-sectional dimensions at the notch site is developed. It is assumed that the work of crack nucleation is proportional to the width of the sample face on which the crack …

Drop weight tear tests (DWTTs) of joints of Ti-6Al-4V alloy obtained by linear friction welding (LFW) were carried out. The specimens had a square cross-section with a U-shaped notch, which was set parallel (parallel notch) or perpendicular (perpendicular notch) to the direction of frictions during LFW (welding direction (WD)). The impact toughness and the fracture morphology were …
