2. Superalloys
Superalloys are designed to perform in extreme environments, exhibiting excellent mechanical strength, resistance to thermal creep deformation, and good surface stability. They are widely used in jet engines, gas turbines, and power plants.
3. Dual-Phase (DP) Steels
Dual-phase steels consist of a soft ferrite phase and a hard martensite phase, providing a combination of high strength and ductility. They are extensively used in the automotive industry for lightweight and crash-resistant components.
4. Transformation-Induced Plasticity (TRIP) Steels
TRIP steels leverage the transformation of retained austenite to martensite under mechanical stress, enhancing strength and ductility. These steels are ideal for automotive parts that require energy absorption during impacts.
5. Twinning-Induced Plasticity (TWIP) Steels
TWIP steels exhibit high strength and excellent formability due to the twinning mechanism during plastic deformation. They are used in automotive and structural applications where high energy absorption is required.
6. Maraging Steels
Maraging steels are characterized by ultra-high strength and toughness, achieved through martensitic transformation and subsequent aging. These alloys are used in aerospace, tooling, and high-performance sporting goods.
7. Shape Memory Alloys (SMAs)
Shape memory alloys can return to their original shape after deformation when exposed to a specific temperature. They are utilized in medical devices, actuators, and aerospace applications for their unique shape recovery properties.
8. Nano-Structured Steels
Nano-structured steels incorporate nano-sized grains, providing superior strength and toughness. These steels are being developed for applications in construction, transportation, and defense industries.
