Characteristics of hybrid microwave sintering of Zn-AI-Cu-Mg alloy

摘要

Hybrid microwave sintering is a promising method to enhance better properties of sintered metallicudalloys. Mixtures of Zn-Al-Cu-Mg elements with 8 wt-%, 12 wt-%, and 27 wt-% fractions of Al were sintered byudhybrid microwave method and compared with conventionally sintered products. Compositional, structural andudthermo-mechanical characteristics of the sintered products were investigated. Analysis of the results confirmedudthe significant technical and economic advantages of hybrid microwave sintering to conventional sintering. Theudcoefficient of thermal expansion (CTE) was reduced from 28.25 um/m'C to 21:23 llm/moC by increasing Aludcontent from 8 wt-% to 27 wt-%.
