| Abstract: | Investigations have been carried out to understand the correlation between Ni content and properties of HPDC cast A384 aluminium alloy in as-cast and heat-treated conditions. Depending on Ni content in the alloy, different Ni-bearing intermetallics were formed. Suitable heat treatment conditions were selected after a series of experiments to obtain optimal mechanical properties. Most of the Ni containing intermetallics found to be stable at solutionizing temperatures which have a dramatic effect on the mechanical properties of alloys after natural and artificial aging. The results showed that, after heat treatment, to achieve higher strength values lower Ni additions are favourable. |
| Description: | Highlights: • Changing Ni content in alloy causes formation of different Ni containing phases. • Formation of Ni containing intermetallics reduce the amount of Al2Cu phase. • Existence Ni bearing intermetallics has a dramatical effect properties of material. • Lower Ni additions are desirable for improving the mechanical properties. |
