Abstract

Now-a-days, light weighting is an important topic for global researchers since it is a significant and efficient way to save energy and reduce carbon emission. There are two major approaches to achieve the purpose of light weighting, one is to introduce the materials with high specific strength and the other one is to vary the design by introducing the topology or lightweight porous structure. Either, of these two approaches was very difficult to be achieved due to the limitation of traditional process. However, due to the maturation of additive manufacturing process, it is possible to realize these two approaches at the same time. In this study, a high specific strength Al alloys was introduced to fabricate samples by using selective laser melting (SLM) process. Meanwhile, a porous structure was introduced to develop the potentially lightweight materials. To further examine the potential of this high specific strength porous material as a lightweight material, the porous samples with different porosity were fabricated. In this research, all of the samples were analyzed and tested carefully, including XRD, SEM and compression test. The relationship between the materials, process, porous structure, microstructure and mechanical properties is explored and discussed in details. Recent Publications 1.
