摘要
本文根据超声波场—声子耦合的超声热处理能量作用机制,研究超声淬火有效频率的物理本质,寻求有效频率计算方法.有效频率和超场波场—声子耦合条件有关,可根据固体物理,量子声学和固态相交理论予以估算.35、45和T10钢的计算结果和实验结果相吻合.
in this paper, the physical nature and the calculus of the effective frequency arestudied from the energy-interaction mechanism of ultrasonic heat-treating for metal mate-rials, i, e, the coupling to the condition of the coupling ultrasonic wave field with phonon isdiscussed and can be calculated by the theories of solid physics , quantum acoustics and solidphase transformation. The experimental results for 35、45 and T10 carbon steels corrrespondto the results which are taken by the calculation
