Abstract
Structural alloys produced by an additive arc process are tested. Impact-flexure tests with subsequent fractographic analysis show that 09Г2С steel switches from ductile to brittle failure below −60°C, but there is no such change for 07Х25Н13 steel and AMg5 alloy down to −150°C. Assessment of the metal failure by means of fractal analysis and a neural network is proposed.
