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 properties of steel can be improved in terms of fatigue, weldability, hardness, wear and corrosion resistance, ductility, and tensile strength by either alloy addition or heat treatment processes.

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 ...

A method that can automatically identify and quantify materials’ microstructure from microscopic images has been developed by the research teams led by Professor Seungchul Lee of POSTECH and Dr.
