摘要：
A comparative analysis of structure, mechanical properties and fracture surfaces of ultrafine grained Inconel 718 obtained by multiple isothermal forging is performed. The refinement of structure down to 80 nm via multiple forging results in the strength increase and in the room temperature plasticity decrease. After the heat treatment the alloy (d=4 mu m) had gained ultimate tensile strength of about 1520 MPa that is 15% higher than that of coarse grained alloy. Room temperature fatigue test for 10(5) cycles revealed the rise of the durability of heat treated alloy by 1.7 times as compared to the coarse grained alloy.
