抄録	Diffusion bonding of titanium-aluminide based alloys(TiAl)and SS400 low-carbon steels was conducted at 600-800℃for 0-60 min using a spark plasma sintering(SPS)system,then bonding strength of the TiAl/SS400 joints were evaluated by shear tests. Compared to previous studies regarding diffusion bonding of TiAl and high-carbon steels,the TiAl/SS400 joints exhibited considerably higher bonding strength. The reason for this is presumably based on increase in bonding area and formation of thinner TiC-based layers at the bonding interface derived from the higher deformability and lower carbon content in SS400. In addition, Vickers hardness measured on the surface of the TiAl and SS400 samples significantly increased after bonding regardless of the bonding temperature, showing that TiAl/SS400 joints with high surface hardness can be fabricated using the SPS system.
