2. 💪 Creep resistance: How well the material holds shape under long-term stress and heat.
3. ⚖️ Mechanical strength retention at high temp: Critical for structural integrity.
4. ☁️ Oxidation and corrosion resistance: For environments like boilers or chemical plants.
5. 🧊 Thermal shock resistance: Ability to survive rapid temperature changes.
6. 🌡️ Thermal conductivity: Some applications need heat dispersion; others require insulation.
7. 💸 Cost and availability: Premium alloys like nickel superalloys can cost hundreds of EUR per kilogram.

Step 3: Compare Thermal Resistant Alloys vs. Heat Resistant Ceramics

Now, it’s time for the classic showdown. Both categories have distinct refractory materials properties, pros, and cons:

• ⚙️ Thermal Resistant Alloys excel in ductility and toughness, ideal for high-stress, dynamic environments like turbine blades. They generally offer better fatigue resistance but might have lower maximum operating temperatures (up to ~1400°C).
• 🏺 Heat Resistant Ceramics withstand ultra-high temperatures (up to 2700°C+) and resist wear and corrosion remarkably well. Yet, their brittleness makes them susceptible to cracking under mechanical shock.

Think of alloys as a sturdy, flexible leather jacket that moves with you, while ceramics are the impenetrable armor you wear when facing the hottest flames but have to move carefully.

Step 4: Consider Environmental and Operational Factors

Will your material be exposed to oxidation, moisture, or aggressive chemicals? For example:

• 🌿 In chemical processing, alumina-based heat resistant ceramics shine due to their inertness.
• 🔥 Turbine engines often demand alloys with chromium and cobalt for oxidation resistance.
