Carbide morphology

Carbide morphology describes the shape, size, and distribution of carbides in steels. It affects wear resistance and formability.

Physical-Chemical Mechanism of Action

Carbide morphology refers to the structure and distribution of carbides in the metallic matrix. This composition affects the mechanical properties of the steel.

Metallurgical Relevance & Welding Risks

Uneven carbide morphology can lead to increased wear and reduced formability. With improper welding treatment, carbides can agglomerate or grow, impairing hardness and toughness.

Shop Practice & Action Instructions

To ensure good carbide morphology, pay attention to correct melting and cooling paths. Use suitable additives like silicon or titanium to distribute carbides evenly. For heavy tool steels, a slow cooling method (t8/5 > 25 s) is recommended.
