## More information

Information about each thermal property can be found below.

#### Thermal diffusivity (mm^{2}/s)

- Each data point shown in the plot is an average of (minimum of) three (3) measurements
- Instrument: NETZSCH LFA 467 HT HyperFlash
^{®} - Purge gas: Argon
- Protective gas: Argon
- Sample thickness: 2.03 – 2.15 mm
- Sample diameter: 10 mm

#### Specific Heat Capacity (J/g-K)

- Each data point shown in the plot is an average of (minimum of) three (3) measurements
- Instrument: NETZSCH STA 449 F3 Jupiter
^{®} - Purge gas: Argon
- Protective gas: Argon
- Sample mass: 91.5 – 93.8 mg

#### Thermal Conductivity (W/m-K)

- Thermal conductivity, thermal diffusivity, specific heat and density are related through, k=\alpha { c }_{ p }\rho. Therefore, best estimation of the thermal conductivity is calculated based on that relation.
- Density of Inconel 740H is assumed to be constant at 8.05 g/cm
