To which bodies are the terms melting and crystallization applicable?

The terms melting and crystallization apply only to crystalline bodies. Their main feature is the presence of a certain melting point (and crystallization). When heated, melting occurs with the absorption of a certain amount of heat without increasing the temperature; when crystallizing in the same amount, heat is released without lowering the temperature.

Amorphous bodies do not have a specific melting point. They soften gradually when heated.
