| Abstract Scope |
Additive manufacturing is the most promising technology to widen the application of aluminium alloys for heat dissipation. It offers to expand the heat echanging efficiency by complicating the internal structure and branching the channels where the heat passes. However, to get a significantly higher efficiency of heat exchangers, complicating the structure is not enough. It is crucial to use an alloy with higher thermal conductivity and higher strength. Developing such powder aluminum alloy requires to take into account the fact that high strength and thermal characteristics have to be achieved after aging or annealing. The possible risk of violation the complex geometry due to high internal stresses means that the material should not demand quenching. This work presents the results of development of selective laser melting and heat treatment for the new Al-Si-Fe alloy, which has a thermal conductivity of 190 W/m·K and mechanical characteristics of medium-strength aluminum alloys. |
