The experiments were carried out with hypoeutectic Al—Fe alloys, subjected to equilibrium solidification from the melt, steady-state solidification Bridgman growth , transient directional solidification in water-cooled and air-cooled molds and rapid solidification laser remelting , thus permitting a significant range of microstructural scales to be examined.

In contrast, even with high values of cooling rate, typical of the laser remelting process, the Al—Al3Fe eutectic is shown to prevail.

It is well known that mechanical properties depend on solidification structures. Heat was directionally extracted only through a water-cooled bottom made of steel SAE It is found that the primary dendrite arm spacing decreases with the increase in tip growth rate and cooling rate.

Pinto, Maria C. Good agreement between numerical and experimental results was obtained in the delimitation of the remelted zone. The work also concerns the analysis of the microstructural and hardness variations throughout samples of an aluminum-copper alloys Al- 15 wt pct Cu submitted to a laser surface remelting treatment. The specimens were examined by optical and scanning electron microscopy. Microhardness measurements were carried out on the transverse section for the resolidified and unmolten regions.
