- •
Comparison of SLM, forging and casting regarding mechanical properties.
- •
Tensile strength and elongation to failure are obtained at RT, 450 °C, 650 °C.
- •
Tensile strength of SLM parts exceed forged and cast parts at room temperature.
- •
At elevated temperatures SLM equal to forged and both better than cast samples.
- •
Dependency of mechanical properties on grain size distribution and orientation.
