Frequently Asked Questions

Expert answers to common material analysis questions from our materials science engineering team

Surface roughness measurement requires understanding key parameters and proper measurement techniques:

• Ra (Arithmetic Average): Mean height deviation from centerline, most common parameter
• Rz (Average Roughness): Average distance between 5 highest peaks and 5 deepest valleys
• Rmax/Rt: Maximum peak-to-valley height within sampling length

Quality Classifications: Ra <0.4μm = excellent surface quality, 0.4-1.6μm = good quality, >3.2μm = rough surfaces

Use contact profilometers for accurate measurement, maintain consistent 0.8mm sampling lengths for most applications, and apply appropriate filtering to eliminate waviness and form errors.

Thermal conductivity varies significantly with material composition, temperature, and microstructure:

• Pure Metals: Highest conductivity - Copper: 401 W/m·K, Aluminum: 237 W/m·K
• Alloys: Lower than pure metals - Steel: 15-50 W/m·K, Titanium: 7-22 W/m·K
• Ceramics: Moderate range - Alumina: 25-35 W/m·K, Silicon Carbide: 120-200 W/m·K
• Polymers: Lowest conductivity - PEEK: 0.25 W/m·K, Nylon: 0.25 W/m·K

Heat Transfer Calculation: Use Fourier's law: Q = k × A × (ΔT/Δx), where k is thermal conductivity, A is area, ΔT is temperature difference, and Δx is thickness.

Consider temperature effects: conductivity typically decreases with temperature in metals but may increase in ceramics and semiconductors.

Hardness scale conversion requires understanding each measurement method:

• Rockwell C (HRC): Diamond cone indenter for hard materials (20-70 HRC range)
• Vickers (HV): Diamond pyramid indenter for all materials (10-3000 HV range)
• Brinell (HB): Steel/carbide ball indenter for softer materials (1-650 HB range)

Approximate Conversions:
• HRC 20 ≈ HV 230 ≈ HB 220
• HRC 40 ≈ HV 400 ≈ HB 380
• HRC 60 ≈ HV 700 ≈ HB 600

For precision applications, use ASTM E140 conversion tables as exact conversions depend on material type, microstructure, and testing conditions.

Stress-strain analysis characterizes material mechanical behavior under load:

• Elastic Modulus (E): Slope of linear elastic region, E = σ/ε
• Yield Strength: Stress at which permanent deformation begins (0.2% offset method)
• Ultimate Tensile Strength: Maximum stress before necking and failure
• Elongation at Break: Total plastic deformation at failure

Common Material Properties:
• Steel: E = 200 GPa, Yield = 250-400 MPa
• Aluminum: E = 70 GPa, Yield = 35-500 MPa
• Titanium: E = 110 GPa, Yield = 240-1400 MPa

Use ASTM E8 tensile testing standards for accurate determination of mechanical properties.

Alloy composition calculations use different models depending on property interactions:

• Rule of Mixtures: For additive properties like density
• Complex Models: For interactive properties involving phase transformations
• Atomic vs Weight %: Atomic% relates to mole fractions, Weight% to mass fractions

Key Calculations:
• Density: ρalloy = Σ(ρi × wi), where ρi is element density, wi is weight fraction
• Elastic Modulus: E ≈ Σ(Ei × Vi), where Vi is volume fraction
• Conversion: Weight% = (Atomic% × Atomic Weight) / Σ(Atomic% × Atomic Weight)

Advanced Considerations: Solid solution strengthening, precipitation hardening, and phase transformations significantly affect mechanical properties beyond simple averaging.
