Vely larger value of ultimate tensile strength, which was above 200 MPa.
Vely greater worth of ultimate tensile strength, which was above 200 MPa. It is actually well known that the improvement inside the thermal stability at elevated temperature is plausible in the formation of higher coarsening resistance from the omega phase () plate formation, but our experimental final results make the relationships extra explicit, which can be inconsistent with earlier studies [138,204].
