摘要

目前的研究重点是粉末冶金加热方式对纯铝阻尼性能的影响。铝粉在40 × 12 × 1.5mm3的液压机中压实，在马弗炉(常规)和微波烧结炉中加热。在双悬臂模式下，在0.1、1和10Hz的不同振动频率下，从室温(RT)到150℃，在恒定应变下，使用动态力学分析仪对样品进行了阻尼测量。结果表明，微波烧结样品比普通烧结样品具有较高的存储模量和阻尼能力。研究并提出了支持这种行为的机制。

Damping characteristics of pure aluminum: A comparison of microwave and conventional sintering

The current research focuses on how heating mode in powder metallurgy affects the damping properties of pure aluminum. The aluminum powder was compacted in a hydraulic press measuring 40 x 12 x 1.5mm3 and heated in a muffle furnace (conventional) and a microwave sintering furnace. The damping measurements were conducted on the samples using a dynamic mechanical analyzer under dual cantilever mode at various vibrating frequencies of 0.1, 1 and 10Hz from room temperature (RT) to 150°C at constant strain. Results demonstrated that the microwave sintered samples exhibit high storage modulus and high damping capacities compared to conventional sintered samples. The mechanisms that support this behavior are investigated and presented.
