| Popis: | In present investigation Ti6Al2Co foams were prepared at different sintering temperatures (1000–1200 °C) using varying amount of space holder contents (40–70%). The prepared foams were characterized in terms of microstructural and mechanical properties. It was found that increase of sintering temperature increased the relative density (RD) and reduced the interparticle gap. The increase of sintering temperature increased the strength, modulus, energy absorbing capacity and microhardness of the samples. The plateau stress and Young’s modulus of prepared foams were found to follow the power law relationship and the constants involved in these equations were found to be in good agreement with the reported values. Further, increment in space holder content, reduced the RD, plateau stress, energy absorption, modulus and hardness of the Ti6Al2Co foams. |
