👉 In the context of materials science and engineering, a "premolder" is a type of material that undergoes a transformation process to increase its strength or improve its mechanical properties. This can be achieved through various methods such as alloying, curing, or thermal treatment. For example, in the case of steel, a premolder could be used for reducing the brittleness and fatigue strength of the steel, while in the case of ceramics, it could be used to increase their hardness and resistance
