A fluid flow control device include a valve body including an inlet, an outlet, and a passageway extending between the inlet and the outlet. A valve trim is at least partially disposed in the passageway of the valve body. The valve trim includes a restrictor having a wall and a plurality of passages extending through the wall. A diffuser is coupled to the restrictor and including a porous body. The porous body is adjacent to the plurality of passages of the restrictor.

Methods for fabricating high-strength aluminum-boron nitride nanotube (Al—BNNT) wires or wire feedstock from Al—BNNT composite raw materials by mechanical deformation using wire drawing and extrusion are provided, as well as large-scale, high-strength Al—BNNT composite components (e.g., with a length on the order of meters (m) and/or a mass on the order of hundreds of kilograms (kg)). The large-scale, high-strength Al—BNNT composite components can be made via wire-based additive manufacturing.
