Fusion Heat Metals

Overview

Engineering reference data for Fusion Heat Metals in material science and properties.

Key Formulas

Stress

$\sigma = \frac{F}{A}$

Force per unit area.

Strain

$\varepsilon = \frac{\Delta L}{L_0}$

Change in length per original length.

Hooke's Law

$\sigma = E \varepsilon$

Stress proportional to strain in elastic region.

Thermal Expansion

$\Delta L = \alpha L_0 \Delta T$

Length change due to temperature.

Variables

Calculation Method

The latent heat of fusion per unit mass can be calculated from the molar value using the following formula:

$$L = \frac{1000 \cdot L_{\text{mol}}}{A}$$

Where:

• $L$ is the latent heat of fusion (kJ/kg)
• $L_{\text{mol}}$ is the latent heat of fusion (kJ/mol)
• $A$ is the atomic weight (g/mol)

Notes

• Unit Conversions for Latent Heat (kJ/kg):

  • $1 \text{ kJ/kg} = 0.23884 \text{ cal/g}$
  • $1 \text{ kJ/kg} = 0.23884 \text{ kcal/kg}$
  • $1 \text{ kJ/kg} = 0.4299 \text{ Btu/lbm}$

• Atomic Weight vs. Atomic Mass:

  • Atomic mass is the mass of a single atom of an element (in atomic mass units, u).
  • Atomic weight is the weighted average mass of all naturally occurring isotopes of an element, relative to 1/12 the mass of carbon-12. It is dimensionless but often expressed in g/mol for calculations.
