Abstract
Alan Lawley’s research in powder metallurgy covered a wide range of topics from atomizing to mechanical properties. Most noteworthy of his efforts was his work in alloy development. Professor Lawley was a strong believer in the relationship between microstructure, processing and properties as it relates to the performance of the material. As new PM processes (such as additive manufacturing) were developed, Professor Lawley helped design new alloys to take advantage of the relationship between the microstructure and the processing. This paper builds on his work in dual-phase steels to develop an alloy for Additive Manufacturing; specifically, for the binder jet process. This work describes a dual phase low alloy steel designed so that it exhibits enhanced diffusion at the sintering temperature leading to high densities. The alloy constituents are formulated, so that upon cooling from the sintering temperature, the transformation products allow the alloy to reach the required mechanical properties. In addition, the microstructure of the alloy can be varied post-sintering, by heat treatment, to give a wide range of mechanical properties that are suitable for automotive components. This alloy, called FSLA (free-sintering low-alloy), was designed and implemented based on the previous work in conjunction with Professor Lawley and demonstrates his continued impact on the PM community.
