What method is used to heat the material? Direct contact with flame?

Heat is generated in vacuum heat treating by a variety of methods, including: Electric resistance heating: This is the most common method of heat generation in vacuum heat treating. A coil of wire is placed inside the furnace and heated by an electric current. The heat is then transferred to the metal parts by conduction. Induction heating: This method uses a coil of wire to generate an electromagnetic field. The electromagnetic field causes the metal parts to heat up by induction. Radiant heating: This method uses a heat source, such as a furnace or a lamp, to emit infrared radiation. The infrared radiation is then absorbed by the metal parts, which causes them to heat up. The specific method of heat generation that is used in vacuum heat treating depends on the type of metal being treated and the desired results. For example, electric resistance heating is often used for heat treating steel, while induction heating is often used for heat treating aluminum.

I watched this to learn about vacuum heat treatment and wow, that was interesting. So it visually effects the steel, but why is that? Does the removal of oxides result in limited distortion because of a more evenly packed grain? Excluding the different treatments, is there any mechanical difference? For instance, if I wanted to forge pearlite, would vacuum treating be optimal for strength or would the difference be negligible/non-existent?

yes
