CoCrFeNi Powder
CoCrFeNi powder, also known as CoCrFeNiMn powder or high entropy alloy (HEA) powder, refers to a material composed of cobalt, chromium, iron, and nickel elements in near-equiatomic ratios. This novel alloy powder displays exceptional properties compared to conventional alloys and has garnered significant interest for various applications.
Overview of CoCrFeNi Powder
CoCrFeNi powder, also known as CoCrFeNiMn powder or high entropy alloy (HEA) powder, refers to a material composed of cobalt, chromium, iron, and nickel elements in near-equiatomic ratios. This novel alloy powder displays exceptional properties compared to conventional alloys and has garnered significant interest for various applications.
Some key features of CoCrFeNi powder include:
High configurational entropy leading to outstanding strength, hardness, thermal stability, and corrosion resistance
Single solid-solution FCC phase microstructure
Excellent strength-ductility combination
High fracture toughness
Good machinability and formability
Resistance to softening at elevated temperatures
Customizable with minor additions of elements like manganese
The unique disorder in the atomic arrangement of CoCrFeNi imparts superior mechanical performance. The near-equal concentrations of the main elements hinder dislocation movement, improving hardness. The multiphase structure provides solid solution strengthening through lattice strain effects.
Composition of CoCrFeNi Powder
The composition of CoCrFeNi HEA powder can be tailored but generally consists of:
| Element | Typical Composition Range |
| Cobalt (Co) | 20-35 at.% |
| Chromium (Cr) | 20-35 at.% |
| Iron (Fe) | 20-35 at.% |
| Nickel (Ni) | 20-35 at.% |
The equiatomic ratio provides maximum configurational entropy but minor deviations do not significantly affect properties. Additions of 1-2 at.% of manganese are common to further improve properties through grain refinement and precipitation strengthening.
CoCrFeNi alloy powder exhibits a unique combination of outstanding properties:
| Property | Values |
| Density | 7.5-8.3 g/cm3 |
| Melting Point | >1200°C |
| Microhardness | 2.5-4 GPa |
| Ultimate Tensile Strength | 500-1300 MPa |
| Yield Strength | 200-1100 MPa |
| Elongation | 10-60% |
| Young’s Modulus | 150-250 GPa |
| Shear Modulus | 65-85 GPa |
| Poisson’s Ratio | 0.21-0.33 |
| Fracture Toughness | >100 MPa√m |
| Thermal Conductivity | 10-30 W/mK |
| Electrical Resistivity | 70-100 nΩm |
| Corrosion Resistance | Excellent in various environments |
The high hardness arises from solid solution strengthening while the FCC structure imparts good ductility. The properties can be tailored through composition adjustments and processing.
Characteristics of CoCrFeNi Powder
