Abstract：IN718 alloy is widely used as parts in fields of aviation，aerospace，nuclear power and petrochemical industries，the performance of final product is related to grain size and δ phase distribution. Three cooling and solution treatment processes were used after the hot-rolling，and the grain size，the δ phase distribution and the related mechanical properties of the final products were analyzed as well. It is shown that the similar δ phase is precipitated on grain boundaries in granular or short-bar manner have been obtained in different processes，the proper grain size and the moderate amount of δ phase precipitation，even the excellent comprehensive mechanical properties can be obtained after online solution treatment.
