Originální abstrakt
The NiTi alloy (Nitinol) has became very important material in last years mainly owing to its shape memory effect which is connected with martensitic transformation from martensitic B19 to austenitic B2 structure and vice versa. The aim of this work is the study of (100) compound twinning mode in B19 martensitic structure of NiTi alloy and its influence on elastic moduli Cij. The computed results show that the studied twinning mode does not have a significant influence to the elastic constant Cij. There is only little decreasing of constant C44 and C66 in system contains twins. The published results can help us to understand of the effect of compound twinning in NiTi shape memory alloy on mechanical properties at the atomic scale.
