Research of hafnium-containing defects in granular nickel EP741NP alloy using electron microscopy
In the process of low-cycle fatigue testing of blanks of turbine disks of turbojet engines made of granular EP741NP nickel alloy, fracture samples were obtained. The fracture area was examined by various electron microscopy methods. Accumulation of rounded high-hafnium micro-particles was detected i...
