Abstract
True picture of short range order of Ni rich Ni-W and Ni-Mo-W alloys has been studied by an atom probe FIM. The presence of solute rich regions having about 50at% solute concentration has been found in the Ni-W alloy and in the Ni-Mo-W alloy. The details of these regions are described. Partitioning of Mo and W atoms in the interior and also at the interface, of (Mo+W) rich regions in ternary Ni-Mo-W alloy has been also studied.
