摘要

The structure and mechanical properties of samples of aluminum bronze of grade BrAZhNMts9-4-4-1 (BrAlFeNiMn) obtained by severe plastic deformation by the method of equal channel angular pressing (ECAP) are investigated. Mechanical tensile tests on a split Hopkinson rod at a deformation rate of about 103 sec –1 are carried out for samples with the original (coarse-grained) and ultrafine-grained structures. It is shown that the refinement of the structure of the aluminum bronze leads to an increase in the dynamic yield strength and to a decrease in the plasticity and in Young’s modulus.
