FIELD: metallurgy.
SUBSTANCE: invention relates to the field of metal casting and pressure processing for the production of complex shaped parts from any metals, including refractory and chemically active ones. A method for liquid forging consists in that a metal melt is obtained by melting a workpiece due to an electromagnetic field of an inductor with the retention of a side surface of the melt on a punch and its subsequent movement at high speed into a stamp, which moves towards the punch until an impact, under the action of which the melt enters the stamp until it is completely filled, causing a water hammer inside the melt, using sensors, both the mechanical movement of the melt inside the stamp and the water hammer inside the melt are detected immediately after the water hammer, the time of which is recorded by the specified sensors, a body part inside the stamp is affected by additional impulse pressure due to the impact of a needle on metal in the stamp, wherein the needle acts as an additional upper punch moving downwards, compressing the melt and crystallizing metal, deforming its structure and providing additional pressing of a part plane to a stamp plane. A liquid forging device contains clutch couplings, rods, a stamp, a punch, pipes, a sliding frame, tracking sensors, a vacuum melting chamber, a needle, a striker, an inductor, a remeltable workpiece mounted on the punch, after obtaining the melt, the punch moves the melt into a stamp pressing chamber, and the stamp moves towards the punch, accelerated by gas pressure, additional pressure on the part body in the stamp is created by the accelerated striker hitting the needle embedded into metal.
EFFECT: invention provides an increase in the efficiency of use and expansion of technical capabilities due to obtaining monolithic or composite parts of the most complex shape with a fine-grained or amorphous structure having high physical and mechanical properties.
