In recent years, microwave processing of metal/alloy powders have gained considerable potential in the field of material synthesis. Microwave heating is recognized for its various advantages such as: time and energy saving, rapid heating rates, considerably reduced processing cycle time and temperature, fine microstructures and improved mechanical properties, better product performance, etc. Microwave material interaction for materials having bound charge are well established, but for highly conductive materials like metals, there is not much information available to interpret the mechanism of microwave heating and subsequent sintering of metallic materials. The present study describes how the thermal profile of electrically conductive powder metal like copper changes with particle size and also with porosity content; in other words, initial green density when the material is exposed to 2.45 GHz microwave radiation in a multimode microwave furnace.

不同粒径和孔隙率纯铜粉的微波加热

近年来，金属/合金粉末的微波处理在材料合成领域获得了相当大的潜力。微波加热以其多种优点而闻名，例如：节省时间和能源、加热速度快、显着缩短加工周期和温度、精细的微观结构和改进的机械性能、更好的产品性能等。 具有束缚电荷的材料的微波材料相互作用是众所周知，但对于金属等高导电材料，没有太多信息可用于解释微波加热和金属材料随后烧结的机制。本研究描述了铜等导电粉末金属的热分布如何随粒度和孔隙率变化；换句话说，
