The melting curve of helium has been calculated over the temperature range of 0–1000 K using molecular dynamics method. Comparisons of the calculated melting curve and the experimental data show that the consistence between the melting curve and the experimental data may reach 500 K. When the temperature is above 600 K, no reliable experimental data have been found for comparison. In addition, the pressures inside the helium bubbles of various sizes existing in metal titanium are calculated and have a comparison with the melting curve. Results show that, at low temperatures, the helium bubbles may be in solid state as the temperature decreases. When the temperature is above 300 K, no solid helium bubble may exist.
