A full range of Vickers microhardness loadings was applied: 10, 25, 50, 100, 200, 300, 500, and 1000 g. Tests were conducted in two areas: 0.5 mm under the surface of the rolled specimen and in the center. The aim was to find the optimal loading range that gives the true material microhardness, also deemed load-independent hardness, HLIH. The results suggest that in the surface area, the reverse indentation size effect (RISE) occurred, similar to ceramics and brittle materials, while in the center, indentation size effect (ISE) behavior was obtained, more similar to metals. This clearly indicated an optimal microhardness of over 500 g in the surface region and over 100 g in the central region of the specimen. Load dependencies were quantitatively described by Meyer\u2019s law, proportional specimen resistance (PSR), and the modified PSR model. The modified PSR model proved to be the most adequate.<\/jats:p>","DOI":"10.3390\/ma17092107","type":"journal-article","created":{"date-parts":[[2024,4,30]],"date-time":"2024-04-30T04:01:52Z","timestamp":1714449712000},"page":"2107","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Load-Independent Hardness and Indentation Size Effect in Iron Aluminides"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3828-8500","authenticated-orcid":false,"given":"Sebastian","family":"Balos","sequence":"first","affiliation":[{"name":"Department of Production Engineering, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8016-9986","authenticated-orcid":false,"given":"Milan","family":"Pecanac","sequence":"additional","affiliation":[{"name":"Department of Production Engineering, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mirjana","family":"Trivkovic","sequence":"additional","affiliation":[{"name":"Department of Production Engineering, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Savo","family":"Bojic","sequence":"additional","affiliation":[{"name":"Department of Production Engineering, Faculty of Technical Sciences, University of Novi Sad, Trg Dositeja Obradovica 6, 21000 Novi Sad, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1533-1016","authenticated-orcid":false,"given":"Pavel","family":"Hanus","sequence":"additional","affiliation":[{"name":"Department of Material Science, Faculty of Mechanical Engineering, Technical University of Liberec, Studentsk\u00e1 1402\/2, 461 17 Liberec, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"735","DOI":"10.1021\/acscatal.6b02603","article-title":"Intermetallic Compounds: Promising Inorganic Materials for Well-Structured and Electronically Modified Reaction Environments for Efficient Catalysis","volume":"7","author":"Furukawa","year":"2017","journal-title":"ACS Catal."},{"key":"ref_2","unstructured":"Askeland, D.R., Fulay, P.P., and Wright, W.J.
