Shape memory alloys (SMAs) have special property of the shape memory effect. After thermal treatment above the martensitic transition temperature, the alloys come back to the original shape when the alloys heat again after having cooled it to the temperature that is lower than the martensitic transition temperature. By means of this property, many industrial parts and systems were produced. Thi…
To safely work with electricity, it is important to have a grasp of the basic theories. Whether we are talking about atomic structure, electrical terms, or measurement devices, understanding the theory of electricity is a key concept.
