Special Issue "Instrumented Indentation Test: An Aiding Tool for Materials Science and Industry"
A special issue of Materials (ISSN 1996-1944).
Deadline for manuscript submissions: 30 September 2021.
Interests: instrumented indentation testing; contact mechanics; micro–macro modeling of the multiphysical processing of materials; microstructure design of materials; microstructure–property–process parameter relationships
It is believed that the instrumented indentation test (IIT) will revolutionize the industry in the next two decades, while continuing to lead to new elucidations about the nature and behavior of materials. It shares the same mechanical fundamentals as a conventional indentation test (IT), but it also permits a multitude of indentation properties, other than hardness, to be extracted in a quick, easy, and nondestructive manner. As such, it can be used either in offline or online manufacturing processes to assess the final mechanical performances of a part or to optimize the most relevant process parameters. IIT is particularly suitable for additive manufactured products, welded joints, and microelectromechanical devices, which generally lack a standard structural assessment. Although IIT can virtually be performed over nano-, micro- and macrodimensional scales, over the last decade, research into IIT has been dominated by nano-IIT studies, which have had a great impact on the progress of materials science and the thin film and coating industry. However, even greater impacts may be expected in the industrial sectors if macro-IIT comes into play, provided that appropriate guidelines are available. Macro-indentation properties correlate more naturally with the familiar tensile-like properties than nano-IIT ones do; thus, the macro-instrumented indentation test will offer an unprecedent viable nondestructive means of measuring tensile-like elastoplastic properties at a local scale in a wide range of metals and engineering alloys. The primary goal of this Special Issue is to present the recent advances in IIT research, with particular attention to macro-IIT achievements. The secondary goal is to provide comprehensive fundamental knowledge on IIT methodologies along with useful guidelines that are not covered by any available national or international standard, to permit IIT techniques to be exploited in new research and engineering fields.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.
