  Heat Treatment Effect on Microstructural, Mechanical and Tribological Properties of Nickel Aluminium Bronze Alloy Manufactured by Laser Powder-Bed Fusion Technique
  Author(s): Fathia Alkelae* and Shinya Sasaki
  
  High density nickel-aluminium bronze alloy (Cu9Al4Fe3Ni) was manufactured using Laser Powder-Bed Fusion Technique (L-PBF), it was investigated regarding the effect of different heat treatment conditions on its mechanical, microstructural and tribological behaviour. Correlations between the microstructures generated (k phases) and the behaviour observed were established. Regardless the heat treatment applied (annealing, tempering, quenching and tempering), friction coefficient, wear loss and hardness have been shown to decrease with increasing heat treatment temperature, while tensile strength and the elongation improved compared to the as-built sample. On the other hand, correlations using increased precipitates content resulting from different heat treatments confirmed the improvement of the material’s mechanical properties at the ex..
