THE FORMING OF COMPLICATED SHAPES BY POWDER METALLURGY SLIP CASTING
The effects of pressure gradients and the resulting density gradients during conventional powder metallurgy pressure compacting are discussed. Steps in the metal powder slip casting process are reviewed, and applications of the process for the fabrication of porous materinls and parts, and also for hollow parts of various shpes are shown. The experimental results of slip casting stainless steel tensile test bars, with two different mold designs, of solid and hollow turbine compressor blades, are described. The test results obtained, heretofore, are with respect to stainless steel tensile bars characterized by a density of 98.6%, a tensile strength of 77,500 psi, and an elongation of 56.6%. (auth)
