Research abstract
The use of aluminum in rocket engine turbo-machinery has not been realized due to strength limitations at elevated temperature. This Phase I SBIR proposal addresses innovative, cost-effective manufacturing techniques for L12 strengthened aluminum alloysthat will exhibit high temperature strength (60 ksi at 400¿F) and structural stability beyond the capabilities of conventional wrought alloys. The proposed program will investigate the influence of incoherent nano-scale nitride particles, incorporated bythe cryogenic milling of L12 strengthened aluminum alloy powder in liquid nitrogen, on high temperature strength retention. Traditional manufacturing process steps involved in the production of cryogenically milled aluminum will be simplified for thepurpose of reducing the cost of small lot sizes: (a) reduced cryogenic milling times, (b) powder handling in
