Abstract：

Accumulative roll bonding for TA1/Q235 in the conditions of different deformations and temperatures was researched by using of Gleeble-1500 thermal analog testing machine.The micro hardness and inter metallic compound formed in accumulative roll bonding were analyzed by means of SEM,X-ray and micro hardness-testing device.The results show that inter metallic compound forms in the interface between two base materials consists of TiC and Ti2Fe.When the deformation temperature is higher than 950 ℃,or the accumulated deformation is more than 150%,the micro-hardness in the interface decreases obviously.Super large deformation can increase bond strength of Ti/carbon steel because of crushing,deformation and dispersing of inter metallic compound.
