摘要

在当今世界，快速成型制造（AM）是最流行的技术之一，并有可能彻底改变制造业。作为该行业的最新进展之一，液态金属打印在工程领域的价值日益凸显。本研究旨在评估两种热处理条件对用该技术生产的 Al-4008 合金的微观结构和机械性能的影响。结果表明，热处理（HT）可增强硅颗粒凝聚和富铁金属间化合物析出，显著提高样品硬度（50%）。密度分析表明，热处理后孔隙率略有下降。拉伸试验表明，热处理后的同向拉伸样品与原样相比表现出脆性，而 HT 则提高了屈服强度（245 兆帕）和极限拉伸强度（294 兆帕）。

Effect of Aging Heat Treatment in an Al-4008 Produced by Liquid Metal Printing

In today's world, additive manufacturing (AM) is one of the most popular technologies and has the potential to revolutionize the manufacturing industry. As one of the most recent advances in this industry, liquid metal printing has a growing value in the engineering field. This study aims to evaluate the effect of two heat treatment conditions in an Al-4008 alloy produced by this technique in the microstructure and mechanical properties. It was concluded that the heat treatment (HT) enhances the Si particle coalescence and Fe-rich intermetallic compound precipitation, increasing the sample hardness significantly (50%). Density analysis showed a slight porosity decrease with HT. Tensile tests indicated heat-treated, same-directionally pulled samples exhibited brittleness compared to as-printed ones, while HT increased both yield strength (245 MPa) and ultimate tensile strength (294 MPa).
