Abstract Scope |
Alloy development for additive manufacturing is relatively slow process due to the need to generate powders to assess the weldability and reactivity of the different materials. In-situ alloying requires optimisation of its parameters prior to assessing the processability of the alloy. In this study a powder metallurgy-based route was incorporated, using elemental powders which were blended, outgassed, and then HIPed. A laser track (bead on plate) was used to assess the processability of different materials. The reactivity of the material (known to influence the meltpool stability and the safety of the powder being studied) was determined using a plume analysis image processing technique that observed the vapour plume generated by the laser. Meltpool observations were performed to assess the cracking suscpetibility of the alloys. Hardness measurements were taken in and outside the meltpool itself. The cracking observations were correlated with solidification models. |
