The properties of steel are influenced by its chemical composition, microstructure, and processing history. Some of the key properties of steel include: Dual-phase (DP): Soft ferrite + hard martensite →

Mechanical Properties

The performance of steel is dictated by its chemical composition and microstructure. : Ferrite – Soft, ductile, magnetic

• Dual-phase (DP): Soft ferrite + hard martensite → high work hardening.
• TRIP (Transformation-Induced Plasticity): Retained austenite transforms to martensite during deformation → excellent formability.

• Ferrite – Soft, ductile, magnetic.
• Austenite – Non-magnetic, high-temperature phase.
• Cementite – Hard, brittle iron carbide (Fe₃C).
• Pearlite – Lamellar mixture of ferrite and cementite; offers strength and ductility.
• Martensite – Very hard, brittle structure formed by rapid cooling (quenching).
• Bainite – Intermediate hardness and toughness.
