Effect of Multi-Variant Thermal Treatment on Microstructure Evolution and Mechanical Properties of AlSi10Mg Processed by Direct Metal Laser Sintering and Casting
Abstract
:1. Introduction
2. Materials and Methods
3. Results
4. Conclusions
- A favorable alloy structure after DMLS process with evenly distributed precipitates against the background of a solid aluminum solution. In the cast, the secretions were located mainly in the interdendritic areas, which caused the occurrence of areas prone to cracks.
- In DMLS samples, in contrast to cast samples, no lamellar precipitates of silicon were observed, which indicates their better resistance to cracking.
- The total proportion of porosity did not exceed 2.38% in the cast samples and was less than 0.03% in the DMLS samples.
- Both printed and cast samples showed similar mechanical properties (hardness) achieved after long ageing time, i.e., 16 h at 170 °C. The maximum hardness was observed for the time of 8 h. In order to shorten the ageing time, the temperature can be slightly increased to approx. 180 °C.
- At temperatures of 200 °C and higher ageing occured, which caused a significant reduction in hardness.
