Özet |
In the present study, weldability of Alumix 231 based composite materials reinforced with Al2O3 and B4C and produced by powder metallurgy route is investigated. Various amounts of (0, 5, 10, and 15% wt.) Al2O3 and B4C powders are added to the pre-alloyed Alumix 231 (Al - 2.5% Cu - 0.5% Mg - 14% Si) powders separately and then mixed in a three-dimensional mixer for 45 min. Powders are compacted and sintered in an argon atmosphere at 640°C for 4 h. Produced blocks are welded by the Tungsten Inert Gas (TIG) welding at 25 V, 197 A and 14 l/min shielded gas flow in commercially pure argon atmosphere. Macro- and microexamination together with some mechanical properties of the welded area are studied. The results show that, although high amount of particles resulted in a decrease in the density, these composite materials can still be welded by the TIG welding method successfully. |
