Vely greater value of ultimate tensile strength, which was above 200 MPa. It is well known that the improvement in the thermal stability at elevated temperature is plausible in the formation of higher coarsening resistance with the omega phase () plate formation, but our experimental final results make the relationships more explicit, that is inconsistent with previous research [138,204].
