项目摘要

Up to now, a lot of damping materials, such as shape memory alloys, magnetic alloys, two-phase alloys and soft alloys, have been developed. The previous alloys, however, are not sufficient for practical applications, because of the low strength and poor dumping properties. Recently, the present research group has developed new Cu-based SM alloys with a high ductility and excellent dumping properties. In the present study, the mechanical and damping properties of these alloys were investigated and a possibility for practical damping materials in some industrial fields, such as microparts in some precision machines etc., was evaluated.The obtained main results are as follows :1.The Damping properties of many specimens with different grain size were examined by dynamic mechanical spectrometer (DMS) in the several conditions on strain and frequency in the applied vibration. It can be concluded that the specimens with large grain size show an excellent damping capacity.2.The damping properties of some specimens with texture were also examined by DMS. It was found that the texture effectively improves the damping capacity.3.The mechanical properties of these texture alloys were evaluated by cold rolling test. It was confirmed that these alloys have an enough formability which will be needed for the practical application.4.An inserting sheet to decrease the vibration generated from speakers in audio system was fabricated on trial. The sheet shows excellent damping properties especially in low frequency field of the applied vibration.

迄今为止，已经开发出许多阻尼材料，如形状记忆合金、磁性合金、两相合金和软合金等。然而，以前的合金由于强度低和倾倒性能差而不足以满足实际应用。近期，本课题组开发出新型铜基SM合金，具有高延展性和优异的倾倒性能。本研究对这些合金的机械性能和阻尼性能进行了研究，并评估了其在一些工业领域（例如精密机械中的微型零件等）中实际阻尼材料的可能性。获得的主要结果如下：1.采用动态机械谱仪（DMS）测试了多种不同晶粒尺寸样品在施加振动的应变和频率条件下的阻尼性能。由此可见，大晶粒尺寸的试件表现出优异的阻尼能力。2.用DMS测试了一些带有织构的试件的阻尼性能。结果发现织构有效提高了阻尼能力。3.通过冷轧试验评价织构合金的力学性能。经证实，这些合金具有足够的可成形性，满足实际应用的需要。4.试制了一种用于减少音响系统扬声器振动的插入片。该板材显示出优异的阻尼性能，特别是在所施加振动的低频场中。
