The manipulation of materials, and to some extent also their systematic classification, form an integral part of the skills and culture of all societies. Yet it took long for proper sciences (e.g., metallurgy, glass technology, polymer chemistry or solid-state physics) to develop out of many processing procedures, tapping the accumulated knowledge about specific material characteristics. In the late 20th century an overarching science of workable materials emerged: materials science. This concept and term originated from major boosts in materials research during WWII and the Cold War, first financed by the U.S. Department of Defense and the Advanced Research Project Agency (ARPA). The COSMAT-Report from 1974, written by the American Presidential Science Advisory Committee's ,,Committee on the Survey of Materials Science and Engineering'' four years after its inception, and subsequent reports heralded in the second institutionalization phase of materials science in the USA and with some delay also elsewhere. As the field continued to expand, the demand grew from within in the late 1990s for disciplinary status.This article sorts these claims from the various camps (by solid state physicists vs. chemists vs. engineers) and sets them in the context of unfolding institutional change. The developments within the German-speaking realm, thus far unduly neglected in these debates, are added. I close with a systematic discussion of eight indicator arguments for or against a convergence of this complex field of research into a single coherent discipline. Against Bensaude-Vincent's (2001: 242) thesis that materials science still is an ''aggregation of fragments of knowledge'', I argue that by 2010 materials science did indeed achieve disciplinary status in a historically rare and enduring process of discipline formation through ''emergence by integration'' rather than by differentiation.

“…In nutshell, the behaviour of the conduction electrons in the neighbourhood of the structural defects is ultimately responsible for the peculiar property of the crystal. Recently, Seeger [43] in an overview proposes the kinks in dislocation behaving as point like 'particles'. They are capable of motion in one direction and are, therefore, suitable objects of statistical mechanics.…”

Samsonov’s Model for Electronic Mechanism of Sintering and its Relevance

In the present review a generalized view of sintering mechanism on the basis of the electronic nature of the chemical species involved has been highlighted. The stable electronic configuration model proposed by G.V.Samsonov is one of the models. In spite of the fact that the model is qualitative, its far reaching impact in explaining liquid phase sintering and activated sintering of real systems can not be minimized. In a way the model holds a premium in its predictive nature , which is so crucial not only in sintering processing, but also in alloy design based on metallic or ceramic systems or composites constituted out of these.
