Abstract
Laser cladding experiments with a hypoeutectic Stellite 6 alloy have b een performed with scanning speeds ranging from conventional values (1 .67 mm s(-1)) up to very fast values (167 mm s(-1)). The evolution of the secondary dendrite arm spacing is discussed using the solidificati on conditions deduced from a two-dimensional heat flux model and the q uaternary Co-Cr-C-W phase diagram.
