Abstract
As an alloying additive, silicon has been shown to be effective in improving the mechanical and physical properties of both iron-carbon and low-alloy PM steels. The benefits of silicon include increasing the hardenability, either alone or in combination with other elements such as molybdenum, chromium, and manganese. These elements can be combined using complex particulate additives, by prealloying, or in combination. The effectiveness of the additives is dependent on the distribution of the elements throughout the material volume, which is determined by the diffusion of each added element during sintering. The distribution of silicon and the other elements was quantified using energy dispersive spectroscopy on multiple alloy compositions. In addition, the effects of diffusion of the additive on hardenability were addressed by estimating the volume percent of the various transformation products in cross sections of hardenability samples using both light and electron microscopy.
