摘要
研究了轧制压下量对ZK60镁合金显微组织及阻尼性能的影响。结果表明,随着轧制压下量增加,ZK60镁合金阻尼性能逐渐增强。在应变振幅为0.01%时,Q^(-1)值由铸态时的0.0127增加至轧制态(压下量为50%)时的0.0159(轧制面)、0.0204(侧截面)与0.0183(横截面)。合金(0002)基面织构强度随着轧制压下量增加而增强,由压下量10%时的6.547增加至压下量50%时的10.690,压下量对合金阻尼性能产生了一定影响;组织中再结晶体积分数增加对阻尼性能的影响起主导作用。
The effect of rolling reduction on the microstructure,damping properties and mechanical properties of ZK60 magnesium alloy were studied.The results show that the damping properties of ZK60 magnesium alloy is improved with the increase of rolling reduction.When the strain amplitude is 0.01%,the Q^(-1) value increases from 0.0127 in as⁃cast state to 0.0159 on rolling surface(RD⁃TD)with the rolling reduction of 50%,0.0204 on side section(RD⁃ND)and 0.0183 on cross section(TD⁃ND).With the increase of rolling reduction,the(0002)basal texture strength of the alloy increases from 6.547 with the rolling reduction of 10%to 10.690 with the rolling reduction of 50%,which brings a certain impact to the damping properties of the alloy.The increased recrystallization volume fraction in the microstructure is the main influencing factor for the damping properties.
