“…For example, increasing the number of pulses and the laser energy density can increase depth of patterned structures; however, it has a detrimental effect on surface finishing due to formation of porosity [51]. DLIP can also generate a steep thermal gradient on the surface, which can cause microcracking, directional recrystallization and phase transformation [42,52]. Thus, it is important to optimize laser parameters to achieve the desirable surface patterns with good quality.…”

“…The presence of m-phase and residual stresses should not be responsible of the decrease in mechanical properties, since there is no difference in the biaxial strength and Weibull modulus in laser treated samples before (LP) and after the thermal treatment (LP+TT). In fact, annealing at 1200°C for 1h is able to relief residual stresses and revert m-phase to t-phase [12]. The relatively small number of samples does not allow to conclusively discern a difference between the LP and LP+TT samples, however, the small difference in values may indicate that residual stresses are very shallow and do not contribute to significant changes in strength.…”

“…The discs that were laser-treated were labelled Laser Patterned (LP) and were further divided into two groups: one group (LP) did not undergo any further treatment after patterning while the other discs (LP+TT) were annealed after the laser treatment. The annealing treatment was performed in an air furnace at 1200°C during 1 hour, with the purpose of eliminating residual stresses and revert the monoclinic phase to tetragonal (further details about the effect of the thermal treatment on LP samples can be found in [12]).…”
