To obtain basic data for high-temperature drying of wood, changes in vibrational properties of green wood of Sitka spruce (Picea sitchensis Carr.) in a high-temperature atmosphere were measured in situ. Young's modulus and loss tangent were measured with vibration tests in an electric oven. Changes in temperature, moisture content, specific Young's modulus, and loss tangent with time were obtained. These changes were investigated by dividing them into four stages.
