Abstract: Nano-structural synthesized materials can be fabricated utilizing intensive milling after combustion synthesis. The Al2O3-TiB2 ceramic composite has been synthesized by aluminothermic reactions between Al, Ti (TiO2), and B (B2O3 or H3BO3). Boric acid (H3BO3) is less expensive than boron oxide, and after being dehydrated at 200°C, boron oxide will be obtained. In this study, Al, TiO2, ...

During solidification of metallic materials, heterogeneous nucleation occurs on substrates, either endogenous or exogenous. The potency the substrates for is mainly dependent upon atomic arrangements substrate surface, which are affected by lattice misfit between and nucleated solid, surface roughness at scale, chemical interaction melt. Extensive examinations metal/substrate (M/S) interfaces s...

This work studies the process feasibility of milling a metal-matrix composite based on Inconel 625 with added NiTi-TiB2 fabricated by direct laser deposition. The is intended for manufacturing turbine blades and it has strength characteristics par those 625. However, addition TiB2 improved its heat wear resistance. material new, machinability not been studied. new was milled end mill cutters, r...
