In this work we present the results of computer simulations molecular dynamics of the metallic alloys: Ni_{33}Zr_{67} and Ni_{50}Zr_{50}. The critical glass-forming temperatures are defined from the behavior change of the Wendt-Abraham parameters of the studied systems. We have found that the increase in the concentration of nickel in the system NiZr leads to displacement of the critical glass-forming temperature in higher temperature region. It is shown that the structural transformations which were observed in the Ni_{50}Zr_{50} system are not related with crystallization processes.
