This study reports a Tool-Narayanaswamy-Moynihan (TNM) simulation on crystallized Zr60Cu25Ni5Al10 amorphous alloy. During a glass transition process, either on heating or cooling, parameters affecting a simulation results remain the same when the physical change during glass transition do not change. Here, we investigated the effect of crystallization fraction occurred on Zr60Cu25Ni5Al10 amorphous alloy after partially crystallized by heating the glassy alloy beyond crystallization temperature. The partial-crystallized samples are for 20 %, 50% and 80% crystals fraction. The results show that the non-linearity parameter, x, increases and the non-exponentiality parameter, β, decreases with higher crystals fraction of the crystallized alloy.
