Abstract
Laser Cladding with nickel aluminum bronze has much promise for the repair and surface engineering of components made from nickel aluminum bronzes and from other alloys. Until recently, comprehensive understanding of how microstructure develops in this alloy, under the rapid rates of cooling typical of laser methods, has been missing. This presentation will summarize our understanding of how microstructures develop in the as-deposited, re-heated and heat affected zones of laser clad nickel ratio, and aluminum content will be given. The difficulties these microstructures impose for residual stress measurement and implications of these microstructures for properties will also be considered.
