Sinter-brazing is an established joining process for powder metallurgy components and is often used inproduction of automotive applications. A successfully brazed joint relies heavily on the interactions betweenthe braze alloy, the joining surfaces, and sintering atmosphere. The widely used braze alloy, Ancorbraze 72(AB72), was designed to alloy with the parent material and locally seal porosity of steel PM part surfaces,thereby preventing significant braze material loss due to infiltration. Brazing performance under differentprocessing conditions will be examined and the influences of flux and iron modifications to the braze alloyon the melting and solidification behavior are explored and characterized.
