Abstract
This paper presents researches of the authors about the influence of the compacting pressure and powder granulation above porous pieces reinforced with steel yarns. This type of pieces have been made from steel powder mixtures ANCORSTEEL 1000 B with controlled granulation reinforced at the buffer zone with massive yarns with Ф= 0, 3 mm and multicore yarns with Ф= 0, 45 mm. The samples have been pressed at 200, 300 and 400 MPa. The pressing was made orthogonally onto the placement direction of the yarns. The compacting has been made in a unidirectional compression mould with section of 7x51 mm. The sintering of samples was made at 1050-1100 C in a controlled argon medium. There were obtained low densities of 5.8… 6.5 g/cm3.
