jäykennetty

Jäykennetty is a Finnish term that translates to "stiffened" or "rigid" in English. It is primarily used in the context of materials science and engineering to describe a process or a state where a substance has been made less flexible or more resistant to deformation. This stiffening can be achieved through various methods, depending on the material in question.

In polymers, for example, jäykennetty might refer to the addition of reinforcing fillers, cross-linking of polymer chains, or a change in temperature that reduces molecular mobility. These processes can significantly alter the mechanical properties of the polymer, making it suitable for applications requiring greater structural integrity. For metals, stiffening can be achieved through heat treatment processes like tempering or by alloying with other elements.

The term can also be applied more broadly to describe any situation where something has become less pliable. For instance, a muscle can become jäykennetty due to exertion or injury, leading to a feeling of stiffness. In a more abstract sense, a policy or an approach might be described as jäykennetty if it has become more rigid or less adaptable. The specific meaning of jäykennetty is therefore dependent on the context in which it is used.
