    摘要: A process for the production of high temperature-resistant metallic components with finely porous walls through which there can diffuse a cooling medium. The component is formed of an alloy capable of oriented eutectic solidification, and is cooled in a controlled mode after short-term sintering so as to form needles or rods extending perpendicular to the wall surfaces, and which are then etched out so as to provide cooling medium passageways.
