K465 Alloy Powder
K465 alloy powder is a nickel-based superalloy that offers high strength and corrosion resistance at elevated temperatures. It is widely used in aerospace, power generation, and chemical processing industries.
K465 Alloy Powder: Composition, Properties, Applications, and Specifications
K465 has become a popular choice for aerospace, power generation, and chemical processing industries where components are subjected to high temperatures or aggressive environments. It allows complex geometries to be 3D printed for optimal performance.
This article provides detailed information on the composition, properties, applications, specifications, availability, processing, and comparisons of K465 superalloy powder for additive manufacturing.
The nominal composition of K465 nickel-based superalloy powder is given below:
| Element | Weight % |
| Nickel (Ni) | Balance |
| Chromium (Cr) | 15 – 17% |
| Cobalt (Co) | 9 – 10% |
| Molybdenum (Mo) | 3% |
| Tantalum (Ta) | 4.5 – 5.5% |
| Aluminum (Al) | 5 – 6% |
| Titanium (Ti) | 0.5 – 1% |
| Boron (B) | 0.01% max |
| Carbon (C) | 0.03% max |
| Zirconium (Zr) | 0.01% max |
| Niobium (Nb) | 1% max |
Nickel forms the base of the alloy and provides a face-centered cubic matrix for high temperature strength. Elements like chromium, cobalt, and molybdenum contribute to solid solution strengthening and enable precipitation hardening.
Aluminum and titanium are added to form gamma prime precipitates Ni3(Al,Ti) to provide hardness and creep resistance up to 700°C. Tantalum provides solid solution strengthening and forms carbides for grain structure control. Boron facilitates precipitation of complex carbides.
The balanced composition of K465 nickel superalloy powder results in a combination of strength, ductility, corrosion resistance, and weldability required for high performance additive manufactured components. The optimized levels of alloying elements can be tailored based on final part requirements.
