### **Product Introduction: Astroloy M (UNS N13017) Premium Powder Metallurgy Superalloy** **Astroloy M (UNS N13017)** is a high-performance, nickel-based superalloy produced via advanced powder metallurgy (PM) processing. It represents the pinnacle of materials designed for extreme temperature and stress environments, offering exceptional strength, creep resistance, and microstructural stability where conventional wrought alloys reach their limits. This alloy is strengthened by a high volume fraction of gamma prime (γ') precipitates, achieved through its optimized aluminum and titanium content. The "M" designation often refers to a modified version with improved processability and consistent properties. Astroloy M is primarily used in the most demanding rotating components of aerospace turbines and is a critical material for pushing the boundaries of engine efficiency and performance. --- #### **Key Features & Advantages** * **Exceptional High-Temperature Capability:** Retains ultra-high tensile, creep, and stress-rupture strength at temperatures up to **980°C (1800°F)** and beyond. * **Superior Microstructural Stability:** Resists grain growth and deleterious phase formation during long-term exposure to high temperatures and stresses. * **Optimized Powder Metallurgy Structure:** The PM process ensures a fine, uniform, and chemically homogeneous microstructure, free from the segregation issues common in conventionally cast high-alloy materials. * **High Gamma Prime (γ') Content:** The primary strengthening mechanism, providing outstanding precipitation hardening that is stable under load at high temperatures. * **Excellent Fatigue Resistance:** Withstands cyclic loading in high-stress environments, which is critical for rotating parts like turbine disks. --- #### **Chemical Composition (Typical Weight %)** The composition is meticulously balanced to maximize γ' formation and overall stability. | Element | Content (%) | Element | Content (%) | | :--- | :--- | :--- | :--- | | **Nickel (Ni)** | Balance | **Molybdenum (Mo)** | 4.5 - 5.5 | | **Chromium (Cr)** | 14.0 - 16.0 | **Aluminum (Al)** | 4.0 - 4.5 | | **Cobalt (Co)** | 16.0 - 18.0 | **Titanium (Ti)** | 3.4 - 3.8 | | **Carbon (C)** | 0.02 - 0.06 | **Boron (B)** | 0.015 - 0.030 | | **Zirconium (Zr)** | 0.025 - 0.050 | **Iron (Fe)** | ≤ 0.50 | | **Manganese (Mn)** | ≤ 0.10 | **Silicon (Si)** | ≤ 0.10 | | **Sulfur (S)** | ≤ 0.015 | **Copper (Cu)** | ≤ 0.10 | *Note: The high combined percentage of Aluminum and Titanium (exceeding 7%) is the key driver for its immense strength.* --- #### **Physical Properties** | Property | Metric Unit | Imperial Unit | | :--- | :--- | :--- | | **Density** | ~8.0 g/cm³ | ~0.289 lb/in³ | | **Melting Range** | ~1330 - 1380 °C | ~2425 - 2515 °F | | **Thermal Expansion Coefficient (20-100°C)** | ~12.8 μm/m·°C | ~7.1 x10⁻⁶ in/in·°F | | **Modulus of Elasticity (Room Temperature)** | ~210 GPa | ~30.5 x 10⁶ psi | | **Thermal Conductivity** | Relatively Low (~11.5 W/m·K at 100°C) | ~80 Btu·in/hr·ft²·°F | --- #### **Mechanical Properties (Typical for HIPed + Heat-Treated Material)** *Properties are dependent on the specific PM processing route (e.g., Hot Isostatic Pressing - HIP) and heat treatment cycle.* | Property | Condition | Value (Metric) | Value (Imperial) | | :--- | :--- | :--- | :--- | | **Tensile Strength, Ultimate** | Room Temperature | 1400 - 1600 MPa | 203 - 232 ksi | | **Tensile Strength, Yield (0.2% Offset)** | Room Temperature | 1100 - 1300 MPa | 160 - 189 ksi | | **Elongation at Break** | Room Temperature | 10 - 20 % | 10 - 20 % | | **Creep Rupture Strength** | 730°C (1350°F) / 510 MPa | > 100 hours | > 100 hours | --- #### **International Standards** Astroloy M is governed by stringent aerospace material specifications due to its critical application. * **AMS 6306:** This Aerospace Material Specification is a key standard for "Bars, Forgings, and Rings, Powder Metallurgy Nickel-Base Superalloy." It covers the requirements for consolidated PM billets and subsequent wrought products. * **UNS N13017:** The Unified Numbering System designation that uniquely identifies this alloy composition. * **OEM Proprietary Specifications:** Major engine manufacturers like **GE Aviation, Rolls-Royce, and Pratt & Whitney** have their own detailed and often proprietary specifications that define the exact processing, heat treatment, and quality control for Astroloy M components used in their engines. --- #### **Product Applications** Astroloy M is exclusively used in the most critical, high-stress rotating components in gas turbine engines. * **High-Pressure Turbine (HPT) Disks / Rotors:** The core application, where the disk operates under immense centrifugal stress at high temperatures. * **Compressor Disks (Rear Stages):** Used in the hottest sections of the high-pressure compressor. * **Turbine Spools and Shafts:** Critical rotating structures that transmit power. * **Blisks (Bladed Disks):** Integrated disk and blade components where material integrity is paramount. * **Land-Based Turbine Disks:** For high-efficiency power generation turbines. --- **Disclaimer:** *Astroloy is a trademark associated with several high-performance alloy manufacturers.
