Abstract

In the heat treatment of aluminum alloys, fluidized bed quenching is an attractive alternative to liquid quenching processes since the part does not develop a vapor barrier during quenching. This lack of a vapor barrier significantly reduces residual stresses and part distortion that often plagues liquid based quenching techniques. The heat transfer rate of the quenching process, however, is lower than can be obtained by liquid based quenchants. The lower heat transfer rate may rule out fluidized bed quenching for some applications due to part geometry or alloy quench sensitivity. This paper proposes a method to determine the applicability of fluidized bed quenching for a given part. In this research, two castings of a given geometry and alloy were analyzed for the feasibility of fluidized bed quenching. The heat transfer characteristics of a fluidized bed quenching system were measured and the quench sensitivities of the alloys were approximated. Computer modeling was then utilized to determine the applicability of fluidized bed quenching for the heat treatment of these castings. Copyright
