.... Moreover, the finer grain size of a powder product was not amenable to the level of creep-rupture strengths required of airfoils. Furthermore, the cast superalloys could be made hollow (to conserve weight) and cast with simple internal passages for cooling. Consequently, P/M technology languished for a few...
