manufacturing sectors in this State. Roughly 75% of traditional PM parts production is focused on automotive applications which is heavily centered on iron-based PM parts. Unfortunately, there has been a decline in iron powder shipments for parts and vehicle sales. This is largely due to the growth of hybrids and electric vehicles, as well as the downsizing of engines and transmissions dictated by tight emission controls/regulations. The most feasible solution for automakers to meet fuel efficiency and/or emissions reduction requirements is to downsize internal combustion (IC) engines. A limiting factor in downsizing is the ability of combustion chamber materials to survive and manage the higher pressures and temperatures associated with increasing power density for a given engine displacement.
In this proposal, the PI is proposing to use powder metallurgy to fabricate precipitate-strengthened copper alloys that are needed for high power density and efficient. It is envisioned that powder metallurgy can effectively be used to fabricate CuNiSi parts whose properties are comparable to wrought products. This will open windows for new product lines and expand the market volume of automotive and electrical PM parts. The strategy presented in this proposal will provide the industry partner with competitive edge and benefits in properties, increase in production volume and energy savings, collectively offering commercial advantages.
