In this paper, the microscopic features of damage and texture of a wheel tread in high-speed rail were investigated by EBSD. The microscopic sample was cut from the wheel tread zone of a used high-speed rail wheel. It was found from the microscopic investigation that the density of austenite distribution is increased near the wheel tread, and the damage voids distribute far away from the wheel tread zone. The texture analysis with two magnify zone indicated that there exists large amount of twin-crystal within the ferrite in the dimension of 20 micrometer, and the dimension of austenite and martensite decreases in the edge zone of the wheel tread.
