PRESSURE TREATMENT METHOD OF LONG WORKPIECES FROM METALS AND ALLOYS |
摘要 |
FIELD: metallurgy.SUBSTANCE: workpiece is arranged in two supporting and moving supports; tensile and compressive stresses are created by movement of the workpiece through a tool with creation of an electroplastic effect by using pulse or direct current. As the tool, a die with equal cross channels is used, and as supports supporting and moving the workpiece and at the same time as a source of pulse or direct current, reversible line motors are used. Tensile and compressive stresses are created with a combination of force action directions; for that purpose, reversing of line motors is performed, and the value of created stresses is controlled by variation of the value of forces developed by the motors.EFFECT: improving mechanical properties of metal due to formation in it of fine-grained equiaxial structure.4 dwg |
