Simulation study of pores and pore clusters in amorphous alloys Co100−xBx and Fe100−yPy

The simulation of microstructure has been done for amorphous Co100−xBx and Fe100−yPy systems, containing 1 00 000 atoms, where x = 10, 18.5, 30 and y = 10, 20, 25. The present work is focused on the point defects like large pores and its grouping in more complicated forms. The simulation predicted existence in significant concentration of these defects, which strongly depends on metalloid concentration and relaxation. Other local characteristics such as volume of pore cluster, angle distribution, etc., were also calculated and yielded a new insight in the short range order of amorphous metal–metalloid alloys.
