Materials Database Description Key:

Material Class – Sub-Category – Material Specification (treatment) @temperature – Data Type  

For example:

Nickel – Inconel Alloys – Inconel 706 (solution-treated & aged) @200deg – ML,YM  

- This indicates that the material :

• has a base constituent of nickel
• is an Inconel Alloy
• is Inconel 706, specifically
• has been solution-treated and aged
• is at 200 degrees Celcius
• contains Multilinear Isotropic Hardening and Temperature-dependent Young’s Modulus data

- The data types are abbreviated as follows:

• AS = Alternating Stress (fatigue)
• ML = Multilinear Isotropic Hardening (stress-strain)
• PR = Temperature-Dependent Poison’s Ratio
• TC = Temperature-Dependent Thermal Conductivity
• TE = Temperature-Dependent Thermal Expansion
• UT = Uniaxial Test (stress-strain for hyperelastic behaviour)
• YM = Temperature-dependent Young’s Modulus

- The Material Classes are as follows:

• Aluminium
• Beryllium
• Ceramics
• Cobalt
• Copper
• Iron
• Magnesium
• Nickel
• Polymers
• Steels
• Titanium
• Zirconium

- Please note:

• Materials which have no temperature reference in their classification are at room temperature (22 degrees Celcius).
• Steels with no treatment reference have had standard quenching and tempering treatment.
• Steels of the same specification, but with different levels of heat treatment, are classified by their tensile strength (TS). For example:

Eg: Steels – Low Alloy – 4340 TS1090 – AS,YM and Steels – Low Alloy – 4340 TS1450 – AS,YM

- indicates that these steels have been heat treated to a different degree, resulting in Tensile Strengths of 1090 MPa and 1450 MPa respectively.
