Mn、Si合金化和退火温度对Fe-Cr-Mo减振合金性能的影响
|
摘要
采用弯曲共振法测量合金的减振性能,研究了添加0. 3%Mn、0. 5%Si元素及不同的退火温度对Fe-Cr-Mo减振合金性能的影响。结果表明,Fe-Cr-Mo合金在900～1100℃退火温度范围内,随着退火温度的升高,阻尼和强度先增大后减小,均在1000℃存在峰值,而冲击吸收能量逐渐减小。同时,0. 3%Mn、0. 5%Si合金元素的添加对Fe-Cr-Mo合金减振性能和力学性能有较大影响。900℃和1000℃退火时,合金阻尼值分别降低10. 6%和16. 8%,1100℃退火时,阻尼值提高8. 1%。900～1100℃退火时,添加0. 3%Mn和0. 5%Si元素使抗拉强度提高;冲击吸收能量在900℃提高9. 1%,在1000℃和1100℃分别降低90. 8%和75. 4%。
Effects of addition of alloy element( 0. 3% Mn,0. 5% Si) and annealing temperature on properties of Fe-Cr-Mo alloy were investigated. The damping capacity of the alloy was tested by using flexural resonance method. The results show that the damping capacity and strength of Fe-Cr-Mo alloy increase first and then decrease when the impact absorbed energy decreases in the range of 900-1100 ℃.Meanwhile,the addition of 0. 3% Mn and 0. 5% Si has great impact on damping capacity and mechanical properties of Fe-Cr-Mo alloys. The internal friction is decreased by 10. 6% and 16. 8%. When the annealing temperature is 900 ℃ and 1000 ℃ respectively. At 1100 ℃,the damping capacity is increased by 8. 1%. The addition of alloy element can increase the strength between 900-1100 ℃. The impact absorbed energy is increased by 9. 1% at 900 ℃,and decreased by 90. 8% and 75. 4% at 1000 ℃ and 1100 ℃,respectively.
