Abstract: | We propose a method for the evaluation of the fracture toughness (K
1C
) of multilayer fusion claddings on compact specimens at elevated temperatures (20, 70, and 300°C) with cladding (in the slot)
of three layers of materials with gradually increasing crack resistance. As the testing temperature increases, the value of
K
1C
decreases for harder and stronger fusion claddings and, vise versa, increases for less strong and softer materials.
