Mastery of high pressure generation technology at the levels required in this work it’s not trivial. Special matrices, with structural configurations that allow a extreme mechanical stress of the materials with which they are constructed, are used to produce that level of pressure. One of the simplest systems for generating static pressures up to 3 GPa (3000 MPa), is piston-cylinder type. In this type of apparatus, sintered highly densified can be produced from particulate matter placed inside a die and under an axial force, pressed between two pistons. In the presente work, the procedure used to manufacture a matrix (chamber) piston cylinder designed to operate at pressures up to 3 GPa (3000 MPa). Subsequently, from the compaction of chips of a 1050 steel (Æ £ 850 µm) in this matrix, the effect of pressure on the compacted microstructure was evaluated. The results obtained showed that: a) The designed matrix can operate at pressures of up to 3 GPa; b) The microstructure compacted under pressures from 1 GPa (1000 MPa) appeared uniform, highly densified and similar to those obtained by conventional methods that generally require the use of pressure and temperature.
