Special Issue Information

Dear Colleagues,

The necessity for modern materials with unique properties has led to the gradual transformation of materials from their single-phase to multiphase compositions. Recent advances in engineering and material processing have led to the emergence of a new class of gradient multilayer materials called functionally graded materials (FGMs). FGMs are a relatively new class of composite materials with a systematic variation of the composition, microstructure, and properties along a predetermined and developed profile. FGMs possess a combination of properties that differ from the properties of the initial materials of the structure and make it possible to adapt the material to the required conditions.

Today, the interest in FGMs is caused by the prospects of their practical applications. Such materials are used in thermal protection systems, for oxidation- and corrosion-resistant barrier coatings that withstand high-temperature gradients, in the design of engine components for aviation and space technology, for active and passive elements of photonics and optoelectronics. The ability to inhibit crack propagation makes the use of FGM useful as personal protective equipment or for energy conversion devices.

This Special Issue aims to provide a platform to explore these interesting topics and to help to gain new scientific insight into the fascinating materials science and engineering of functionally graded materials.

This work presents a study on the additive manufacturing of functionally graded metal-ceramic materials based on Ti64 with boron fibers and particles. For the first time, the phase composition of the obtained composite was investigated using synchrotron radiation. It was shown that during laser exposure and in situ synthesis, boron dissolves in the titanium matrix, forming secondary compounds such as TiB and TiB2. An increase in the microhardness of the formed material compared to the titanium alloy was established. High-speed impact tests on the Ti64-B samples were conducted using an electrodynamic mass accelerator. It was shown that the use of boron fibers in the metallic matrix reduces the depth of the crater created during impact testing by 40% compared to the Ti64 reinforcement-free coating. Full article
