this paper discusses the cost and the quality aspects of pm parts for structural applications. the cost considerations include a shorter processing path, the production of near-net-shape components, the most efficient use of raw materials and energy, the fabrication of complex shapes with close tolerances and assembling which is possible before sintering. the quality considerations are the homogeneous structures with (almost) no segregation, the fine microstructure, the controlled density and porosity, the good surface finish, the possibility of obtaining non-equilibrium structures, and the fabrication of metal-matrix composites. 6 refs
