Interstitial solid solution formation

Interstitial solid solution: Small atoms like carbon or nitrogen fill interstitial sites of the metal, increasing strength but potentially affecting durability.

Physical-Chemical Mechanism of Action

Small atoms like carbon or nitrogen fit into interstitial sites of the metal. This alters the crystal lattice and atomic arrangement.

Metallurgical Relevance & Welding Risks

This solid solution formation increases strength but can also cause durability issues. Too much interstitial content can harden the material and impair its toughness.

Workshop Practice & Instructions

When welding, it is important to control the interstitial content. Use appropriate shielding gas mixtures and pay attention to proper cooling steps. For highly hardened steels, slow cooling may be necessary.
