The experiment results show that the damping capacity of deformedMartensite first decreases sharply and then keep constant with the increase of frequency at the low strain amplitude;
结果表明，当应变振幅较低时，形变马氏体的阻尼值随频率的增加先急剧下降至一定值后趋于稳定；

The deformed band and transformed band are made up of very fine martensite laths, its hardness is much higher than that of the as-quenched specimen.
