Abstract
We observed in-situ the penetration of ice by a brass wire with a diameter of 0.25mm. Both vapor bubbles and water droplets were observed in ice after wire cutting at pressures between 0.1MPa and 0.6MPa. Analyzed wire velocities were roughly constant at pressures higher than 0.4MPa. However, this was not the case at pressures lower than 0.3MPa. Furthermore, we analyzed the relationship between wire velocities and the ratio of vapor contact to the length of wire. Under 0.2 MPa, the wire velocities increased with decreasing ratio of vapor contact to the length of wire. Therefore, we concluded that wire velocities were inhibited by the formation of vapor bubbles.
