摘要

本研究通过实验研究了以不锈钢 316 L、工具钢 1.2709、钛合金（Ti-Gr.2）和铝合金（AlSi10Mg）为基础材料的添加制造（AMed）FCCXYZ 晶格结构的机械性能。相对密度（RD）从 0.11 到 0.36 的晶格结构根据 RD 的不同显示出不同的压缩破坏模式。在低相对密度时，可观察到逐层坍塌模式，而在高相对密度时，则可观察到块体破坏模式。我们建立了一个 Gibson-Ashby 模型，以准确预测 FCCXYZ 晶格结构在不同 RD 下的性能。本研究中的发现将为设计金属 AM 中的能量吸收部件提供宝贵的参考。

Mechanical analysis of SUS316L, tool steel, Ti, and AlSi10Mg lattice structures manufactured by laser-powder bed fusion for energy absorption design

This study experimentally investigates the dependence of mechanical properties of an additively manufactured (AMed) FCCXYZ lattice structure on base materials of stainless steel 316 L, tool steel 1.2709, titanium alloy (Ti-Gr.2), and aluminum alloy (AlSi10Mg). Lattice structures with relative density (RD) from 0.11 to 0.36 show different compressive failure modes depending on the RD. A layer-by-layer collapse mode is observed at low RD, whereas a bulk failure mode is observed at high RD. A Gibson-Ashby model is developed to accurately forecast the performance of FCCXYZ lattice structures at different RDs. The discoveries presented in this study will be a valuable reference for designing an energy-absorbing component in metal AM.

期刊介绍： The aim of the Journal of Manufacturing Processes (JMP) is to exchange current and future directions of manufacturing processes research, development and implementation, and to publish archival scholarly literature with a view to advancing state-of-the-art manufacturing processes and encouraging innovation for developing new and efficient processes. The journal will also publish from other research communities for rapid communication of innovative new concepts. Special-topic issues on emerging technologies and invited papers will also be published.
