Abstract:

Regularities of impact fracture of materials with BCC lattice structure (steel 10), FCC lattice structure (aluminum alloy AK4-1) and hexagonal lattice structure (titan Grade 4) in the initial state and after ECAP in sub microcrystal state have been established. Impact tests were conducted in the wide temperature interval.. It was shown, the crystall lattice tipe of ultra grained materials determine the character of the impact strength temperature dependence and also fracture mechanism.
