Layered metal composites with high resistance to brittle fracture at low temperatures
Abstract
The structure of the interlayer boundaries of 7-layer composites based on the 09G2S low-alloy mild steel and the EP678 maraging steel obtained by hot rolling is studied. The characteristics of impact strength and dynamic crack resistance of a layered composite are determined by the method of instrumental impact tests in the temperature range from room temperature to -196 °C, the features of the fracture surfaces of impact samples are studied, and finite element modeling of the process of crack growth in a layered composite is carried out.
