| description | The invention discloses a strengthening and toughening treatment method for an additive manufacturing metal material. The strengthening and toughening treatment method comprises the steps that a to-be-treated metal workpiece prepared through an additive manufacturing method is obtained; forming a packaging layer on the surface of the to-be-treated metal workpiece to obtain a packaged workpiece; and after the packaging workpiece is annealed at the pressure of 1-10 GPa and the temperature of 550-1800 DEG C, the packaging layer is peeled off, and the strengthened and toughened metal workpiece is obtained. By means of the method, the defects of metal workpieces produced through additive manufacturing, such as pores, cracks and structure non-uniformity, can be eliminated. The material prepared by the method has relatively high yield strength and relatively good plasticity. The invention further discloses the strengthened and toughened stainless steel workpiece prepared through the method.
