A method of consolidation of powder materials by means of a device provided with a gastight operating chamber, a press coupled to a first electrode and to a second electrode, wherein the consolidated powder is located in a die, between the electrodes, wherein the press exerts pressure on the powder with the first electrode and the second electrode, wherein a circuit comprising a power supply unit is connected to the first electrode and the second electrode, to close the flow of the current of the power supply unit via the first electrode the second electrode, and the consolidated powder, wherein the consolidated powder is subjected to pressure simultaneously with excitation with current pulses, characterised in that the voltage applied to the powder in pulse peak is within the range of 50 V to 900 V, and the pulse duration is shorter than 300 μs, and the consolidation of the powder is performed in at least two steps, wherein, gas from the operating chamber is being vacuumed until gas pressure in the operating chamber is not higher than 10 -5 Pa, then in the first step a pressure of the press corresponding to pressure on the powder within the range of 2 MPa to 15 MPa is applied, while the values of pulse current, pulse duty cycle and repetition frequency are chosen such that the temperature of the powder was constantly in the range of 0.05 to 0.3 of melting temperature of the powder, while gas is constantly vacuumed and gas pressure is constantly measured, then when after initial rise, the gas pressure again reaches a value not greater than 10 -3 Pa, in the second step a pressure of the press corresponding to pressure on the powder within the range of 15 MPa to 200 MPa is applied, and the values of pulse current, pulse duty cycle and repetition frequency are chosen such that the temperature of the powder was constantly in the range of 0.6 to 0.9 of melting temperature of the powder, and the second step is performed with simultaneous measurement of shrinkage of the powder, and it is terminated when during a predefined time the shrinkage is lower than a predetermined threshold value, wherein predefined time is within the range of 15 to 60 seconds and predetermined threshold value is lower or equal 10 μm. gas from the operating chamber is being vacuumed until gas pressure in the operating chamber is not higher than 10 -5 Pa, then in the first step a pressure of the press corresponding to pressure on the powder within the range of 2 MPa to 15 MPa is applied, while the values of pulse current, pulse duty cycle and repetition frequency are chosen such that the temperature of the powder was constantly in the range of 0.05 to 0.3 of melting temperature of the powder, while gas is constantly vacuumed and gas pressure is constantly measured, then when after initial rise, the gas pressure again reaches a value not greater than 10 -3 Pa, in the second step a pressure of the press corresponding to pressure on the powder within the range of 15 MPa to 200 MPa is applied, and the values of pulse current, pulse duty cycle and repetition frequency are chosen such that the temperature of the powder was constantly in the range of 0.6 to 0.9 of melting temperature of the powder, and
