Selective laser melting of high strength Al–Cu–Mg alloys: Processing, microstructure and mechanical properties

Predictive models for physical and mechanical properties of Ti6Al4V produced by Selective Laser Melting

“…When comparing the mechanical and physical properties results obtained in this study with the ones found on literature, several similarities can be found. Regarding density some previous works on different materials produced by SLM [1,3,4] and also for Ti6Al4V [2,7] already state that by finding adequate processing parameters it is possible to obtain parts with an almost full densification (near to 100%), as achieved in this work.…”

“…Between two successive powder layers, a laser beam is used to scan over the layer using the parameters previously defined [1,2]. This technology offers several advantages compared to conventional routes, such as low material waste, high production flexibility that allows an extraordinary freedom when regarding geometry and materials design, being an excellent process to obtain functionally graded materials, suited for parts with local functional requirements [3,4].…”

“…In this sense, several studies have been made concerning SLM processing parameters and its physical, mechanical and microstructural properties, for different kinds of materials [3,8,9]. Even for titanium alloys it appears that some investigations have been made in order to understand and find the optimal processing parameters for this technology.…”

Low temperature annealing dedicated to AlSi10Mg selective laser melting products

“…It is based on local melting of metallic powders, deposited in a uniform bed, by a high power laser beam. The high power transferred by the laser to the melt pool and its small size locally produce an extremely high energy density, for short time, which leads to high heating and cooling rates [1]. These induce a very fine microstructure and solid solubility extension, that strongly affect the material properties.…”

Tensile Properties of Al-12Si Fabricated via Selective Laser Melting (SLM) at Different Temperatures

“…The SLM process is controlled by several process parameters in order to produce components without defects such as pores or cracks [8][9][10]. However, most of the work has been focused on selected process parameters that define the energy density, namely, laser power, laser scan speed, layer thickness, spot diameter of the laser, and hatch distance [11,12]. In addition, hatch style also plays a significant role in the SLM fabrication process [13].…”
