*JSC «Motor Sich» (Zaporizhia, Ukraine)**Zaporizhzhya Polytechnic National University (Zaporizhzhia, Ukraine) УДК 621.74.045:669.24:21.981 Research has established that the application of the technological operation of hot isostatic pressing (HIP) to blades made by the equiaxial casting method from heat-resistant nickel alloy ZhS3DK-VI modified with ultradisperse Ti (C, N) particles allows for minimizing the presence of defects of foundry origin and thus ensure the required level of complexity physicomechanical and operational properties of finished products. The investigated working blades of the fan turbine (both before and after GIP) meet the requirements of OST 1 90126-85 in terms of chemical composition, structure, and mechanical and heat-resistant properties. The values of the angle of bending on the studied blades are within 98...1070. There are no cracks.During the operation of hot isostatic pressing, "healing" of pores and cracks occurs. In the structure of the examined blades after the GIP, micropores, and rickholes are practically absent. The size of the macro grain in the feather of the studied blade is ~0.75...2.0 mm, which is ~2 times smaller than in the tail part. An accumulation of carbonitride particles up to 16 μm in size was found in the structure of the blades (both in the feather and in the shank). The distance between the axes of the second-order dendrites in the feather of the blades is approximately ~1.5 times smaller than in the tail part.   References 1. Sims, Ch. T. (1995).
