Summary

In the present work, the near–net–shape manufacturing of Ti–Al–O–C composites by a combination of indirect three–dimensional printing and pressureless reactive melt infiltration process was explored. A porous ceramic preform was fabricated by printing a powder blend of TiC, TiO2 and dextrin ((C6H10O5)n). The printed preform was pyrolysized and presintered in inert atmosphere at 800CC and 1400°C, respectively. The printed and presintered preforms contained a bimodal pore size distribution with intra–agglomerate pores (d50= 0.7 urn) and inter–agglomerate pores (d50 = 30 μum), which were subsequently infiltrated by aluminium melt spontaneously in argon above 1050°C. A redox reaction at I400CC resulted in the formation of dense Ti–Al–O–C composites mainly composed of Ti3AIC2, TiAI3, Al and AI2O3, which attained a bending strength of 320 MPa, a Young's modulus of 184 GPa, and a Vicker's hardness of 2.5 GPa.
