Noun1.heat of fusion - heat absorbed by a unit mass of a solid at its melting point in order to convert the solid into a liquid at the same temperature; "the heat of fusion is equal to the heat of solidification"
heat of transformation, latent heat - heat absorbed or radiated during a change of phase at a constant temperature and pressure

When we heat the sample a second time, we should see a new heat of fusion that will be higher than the one we saw on first heat.
The use of a latent heat Eutectic aluminum silicon alloy, AlSi12, is a striking phase change material because of its temperate melting temperature, high thermal conductivity, and high heat of fusion. n.
[DELTA][H.sub.sample] is the heat of fusion of the sample (PC powder or billet/sheet) and [DELTA][H.sub.PC single crystal] is the heat of fusion of the single crystal of PC taking the standard heat of fusion [DELTA][H.sub.PC] = 109.8 J/ g for 100% crystalline PC [16].
Nylon 6 were more crystalline than nylon 612, which showed about 30 J/g less heat of fusion. As nylon 6 content increased in the blends, heat of fusion values of the blends increased (Table 4).
For the pristine DR1, a major crystal melting peak at 168[degrees]C is indicated (a small hump around 144[degrees]C is also observed, which may arise from impurities) with a large heat of fusion, [DELTA]H = 87.4 J/g.
Thermal energy is stored primarily as latent energy through the heat of fusion associated with phase change of the encapsulated PCM.
There is flexibility in the choice of phase-change temperature range and latent heat of fusion. The recommended phase-change temperature range is from 25[degrees]C to 27[degrees]C (77[degrees]F to 80.6[degrees]F) and the latent heat of fusion is 23,0132 J/kg (98.9 Btu/lb).
The obtained results showed, that melting temperature, glass transition temperature, heat of fusion and crystallinity of the material decrease whereas tensile strength and temperature of thermal decomposition increase with PEVA cross-linking.
Both the particle size dependent melting temperature and latent heat of fusion were observed.
Tool life is expected to be better r than the aluminum permanent mold process due to the lower latent heat of fusion of magnesium alloys and the very low solubility of iron in magnesium.
In this study, we examine the burning of large candles, with no scent or dye added, by looking at the energy of combustion, the specific heat capacity, and latent heat of fusion. This allows us to determine how much energy is getting from the flame to the wax in the burning process.
