Area of Science:

  • Materials Science
  • Metallurgy
  • Surface Engineering

Background:

  • Timetal 834 is an advanced alloy requiring surface modification for enhanced properties.
  • Nitriding is a crucial surface treatment for improving wear and corrosion resistance.
  • Understanding the microstructure of nitrided layers is key to optimizing performance.

Purpose of the Study:

  • To characterize the microstructure of Timetal 834 before and after glow discharge nitriding.
  • To analyze the layered structure and phase evolution within the nitrided layer.
  • To determine the nitrogen distribution and identify phases in the nitrided zone.

Main Methods:

  • Light microscopy for overall microstructural observation.
  • Analytical transmission electron microscopy (TEM) techniques including SAED, EDS, EELS, and EFTEM.
  • Cross-sectional thin foil preparation for detailed TEM analysis.

Main Results:

  • The as-received alloy comprises alpha and beta phases with Zr5Si4 silicide precipitates.
  • The nitrided layer exhibits a gradient in nitrogen content.
  • Distinct sublayers were identified: delta-TiN (outermost), delta'-Ti2N and epsilon-Ti2N (intermediate), and alpha(N) solid solution (innermost, up to 14 at% N).

Conclusions:

  • Glow discharge nitriding effectively modifies the Timetal 834 surface.
  • A complex, graded microstructure with specific titanium nitride phases and a nitrogen-rich solid solution is formed.
  • The detailed microstructural analysis provides insights for tailoring surface properties through nitriding.
