Chromium Nitride Precipitates: Particle Size 10-100 nm

Component Specifications

Definition

Chromium nitride precipitates are microscopic crystalline structures of chromium nitride (CrN or Cr2N) that form within the matrix of high-purity ferrochromium nitride alloy powder during controlled cooling or heat treatment processes. These precipitates act as dispersion strengtheners, improving mechanical properties such as hardness, wear resistance, and thermal stability in the final alloy product.

Working Principle

Chromium nitride precipitates form through a precipitation hardening mechanism where chromium and nitrogen atoms combine to create stable nitride phases within the alloy matrix during controlled thermal processing. These precipitates create obstacles to dislocation movement, thereby increasing the material's strength and hardness through dispersion strengthening.

Materials

High-purity chromium (Cr) and nitrogen (N) in stoichiometric ratios to form CrN or Cr2N phases within a ferrochromium alloy matrix, typically with chromium content >65% and nitrogen content 1-5%.
