Abstract

In this paper, Effect of different contents of Ce on the Mechanical Properties of ZK20 magnesium alloy and thermal deformation behavior, through the use of room temperature tensile and compression test thermal simulation, analysis Ce element is present in the form of ZK20 magnesium alloy and its alloys Mechanism the results show that: in the experimental range (0%~0.68%Ce (mass fraction)), with the addition of Ce addition amount of 0.7% of the best mechanical properties of alloy extrusion state, room-temperature tensile strength of 261MPa, yield strength 198MPa, elongation of 24.6%. 280 ×4h annealing process enables to improve strength and ductility of the extruded alloys, tensile strength reach 272MPa, yield strength of 209MPa, elongation of 26%. Cerium was added to make ZK20 alloy brittle fracture to the part of the dimple mixed fracture transition.
