Precipitate

Hi,
I have a model that was created like this in atomsk:
atomsk --create fcc 3.562 Fe orient [100] [010] [001] ^
-duplicate 100 50 6 ^
-select in sphere 0.3box 0.5box 0.5*box 7.124 ^
-remove-atoms select ^
Fe1.lmp

atomsk --create fcc 2.91 Cr orient [100] [010] [001] ^
-duplicate 100 50 6 ^
-select out sphere 0.3box 0.5box 0.5*box 7.124 ^
-remove-atoms select ^
-shift 19.56 16.3 1.956 ^
Cr1.lmp

atomsk --merge 2 Fe1.lmp Cr1.lmp FeCr1.lmp

when I read data to my script in LAMMPS, the precipitate changed to pure dislocation after the relaxation in the 300K temp. how can I solve this problem?

Thanks
