Abstract Scope |
It is an established knowledge that different alloying element play specific role in influencing the microstructure and properties of a materials. Material characteristics including; corrosion and impact performances can be optimised by designing new wire compositions or modifying existing ones.
Wire mixing technique has been successfully applied in modifying the deposited material properties in functional graded parts and in modifying composition of aluminium alloy to eradicate solidification cracking. Utilisation of Tandem-GMAW process provides an opportunity of realising this technique; using off-the-shelf filler materials. This potentially provides a cost effective way of actualising the design of improved WAAM material compositions.
This study investigates the mixing of 2.25Cr-1Mo and MoNiCr, with a view to harnessing their corrosion and low temperature toughness characteristics respectively, to achieve a composition with relatively improved performances.
The modified composition achieved showed marked improvement in both corrosion and charpy performances, compared to the starting compositions. |
