摘要：
The influence of the volume fraction of tempered martensite on magnetomechanical damping of theferritic matrix in dual-phase alloys was studied.The experimental results showed that（1）dual-phase damping alloy is of good combination of strength and toughness: （2）good damping ca-pacity(Q;≥5.0×10;)can be obtained in dual-phase alloys only when the volume fraction oftempered martensite was controlled properly.The effect of martensite on magnetomechanical damp-ing of the ferritic matrix was analysed.The damping capacity of dual-phase alloys was related to thevolume fraction V;of tempered martensite by Q;sup>-1=Q;sup>-1 （1-V;/1+BV;）at small vibration strainamplitudes ε;≤5.0×10;.
