- MAX phase foams from commercial Ti2AlC powder were prepared by a novel powder processing method using raw sugar as space-holder. Manufacturing MAX phase foams using this method involves mixing Ti2AlC powder with raw sugar, pressing the mixture to form a green body followed by space-holder removal and sintering. Green bodies were formed using cold uniaxial pressing and porosity was controlled varying the size and amount of the raw sugar space-holder. Three different space-holder particles sizes in the range of 250-1000 mum and four different volume amounts (20%, 40%, 60% and 80%) of space-holder were studied. The foams produced were characterized, and the size distribution and amount of resulting porosity was compared with the theoretically expected values. Optimal conditions using this novel processing technique for this material were established aiming towards controlling the final microstructures and properties, of porous Ti2AlC MAX phase.
