A novel method for forming “programmed” mechanical properties in local components of a part by controlling the microstructure of the alloy under additive production is suggested. It is shown that the thermal fields acting during the additive production may be used for manipulatin ...
Inconel 718 is a nickel-based superalloy commonly used in aircraft engine and nuclear applications, where components experience severe mechanical stresses. Due to the typical high temperature applications, Thermo-Mechanical Fatigue (TMF) and creep tests are common benchmarks for ...

Functionally graded Inconel 718 processed by additive manufacturing

Crystallographic texture, anisotropy of microstructure and mechanical properties

Additive manufacturing offers a unique way of anisotropic microstructure control with a high degree of design freedom. This study demonstrates that application of suitable process parameters and laser sources in selective laser melting may favour either one sharp single component ...
Additive manufacturing (AM) technologies are known to allow the production of parts with an extreme degree of complexity, enabling design and functional part optimization. However, the resulting microstructures and mechanical properties of AM materials are not well understood due ...
