摘要
研究了两种成分的340MPa级烘烤硬化（BH）钢的Snoek—（SKK）阻尼发现用通常范围的频率测量内耗时，BH钢的SKK峰激活能（H）明显偏大；用1．7Hz的较高频率测量时，二者中含C量较高（0．
The Snoek-K- ster(SKK) damping in two bake hardening (BH) steels of 340 MPa class has been studied. It is found that the activation energies(H)of the middle-temperature peaks measured with a general range of frequency are obviously larger than that of SKK peak,and that there are double peaks in all the curves of Q-1- T of the steel containing 0.024%C which is one with higher content of carbon in both the steels, when the measurements were conducted with frequencies ＞1.7 Hz. The results were discussed in detail.
