- •
The data of Sa obtained at various deposited energies can be regressed by a concave curve.
- •
The penetration thicknesses of MZ and HAZ and the sum of the thicknesses of these two zones can be expressed as a function of deposited energy.
- •
The mechanical properties of hardness and reduced modulus are affected by the values of these three thickness parameters.
- •
Effect of microstructure on specimen with and without H.T. are discussed.
