ABSTRACT
Knowledge is the acquisition of awareness or familiarity of a subject or skill through experience, by assimilating information. The experience may be theoretical through education, or it may be practical. When we talk about scientific knowledge, we understand it comes from a systematic experimentation or study of any system. Previously gathered knowledge or information may also be utilised to explain any observation or phenomenon, resulting in new knowledge. In the case of materials systems, the behaviour of materials could be explained by the knowledge of fundamental physics and chemistry, and that would lead to knowledge of the particular materials system. But this may not be true for all materials systems. The systems whose response depends on several variables and interaction between the variables makes the system complex enough to be explained completely using the fundamental science. Steel and many alloy systems are examples of such materials. In such cases expressing the systems’ knowledge mathematically becomes difficult.
