Metal matrix composites

In metal matrix composites (MMC) development, arc melting furnaces facilitate the blending of metals with ceramics to create high-strength materials with high stiffness. Precise process parameter control and homogenization ensures the desired properties are uniformly distributed throughout the composite. TiB2 is a popular choice for modification of Ti alloys due to the in-situ formation of TIB phase. Phase transformation and precipitation during the additive manufacturing process can cause cracking due to additional stresses which accumulate in addition to thermal stresses. That is why we decided to perform the in-situ phase transformation during arc melting process in arcMELTER. In addition to obtaining the feedstock for atomization which is unavailable at the market our team could test the properties of arc caster metal matrix composite which formed spectacular dendritic structure. These results demonstrate the potential of arc melting technology in the development of advanced metal matrix composites with optimized properties for demanding applications, such as aerospace and automotive industries. Further research will focus on refining the process to enhance material properties further and exploring the possibility of incorporating other ceramic reinforcements into Ti alloys and using them in additive manufacturing.

Metal Additive Manufacturing / 3D Printing 101
Additive Manufacturing is a process of creating objects by adding material layer by layer, in contrast to traditional subtractive methods that remove material from a solid block. Metal Additive Manufacturing specifically involves the use of hard-to-machine metals to produce parts and components using bottom-up approach. This method allows for greater design flexibility, material efficiency, and the production of complex geometries that would be impossible or extremely difficult with conventional manufacturing techniques.
