The figure shows the evolution of the microstructure of the melt pool under the influence of the simulated transient temperature field. Nucleated grains are represented in pink-purple plots, while ...

The study includes the manufacturing process of super-invar alloy of WAAM, the relationship between micro-structure and G/R, the mechanical properties and the CTE. The main transfer mode of liquid ...

Superalloys are materials designed to perform under extreme conditions, such as high temperatures and pressures, making them ideal for applications in high-speed flight environments. Inconel 718 is a ...

Wire arc additive manufacturing allowed this robot arm at ORNL to transform metal wire into a complete steam turbine blade like those used in power plants. Credit: Carlos Jones/ORNL, U.S. Dept. of ...

Lincoln Electric Additive Solutions has recently delivered its first aerospace tool with the facesheet 3D printed in Invar. Although the design of the tool has been described as “traditional,” by ...
