It was found that the addition of Mo and Ni to the FeAl20Si20 alloy results in the formation of the AlMoSi phase compared to the three-phase FeAl20Si20 alloy, which initially contained FeSi, Fe3Si, and Fe3Al2Si3 phases. All the investigated alloys increased their hardness, reaching up to 1401 HV 1 for the FeAl20Si20Mo5Ni15 alloy, which contained in total 58.5% of the FeSi and Fe3Al2Si3 phases. As a result, all the prepared alloys showed one order magnitude lower wear rates ranging from 3.14 to 5.97\u00b710\u22126 mm3\u00b7N\u22121\u00b7m\u22121 as well as significantly lower friction coefficients compared to two reference tool steels. The alloys achieved high compressive strengths (up to 2200 MPa); however, they also exhibited high brittleness even after long-term annealing, which reduced the strengths of all the alloys below approximately 1600 MPa. Furthermore, the alloys were showing ductile behavior when compressively tested at elevated temperature of 800 \u00b0C. The oxidation resistance of the alloys was superior due to the formation of a compact Al2O3 protective layer that did not delaminate.<\/jats:p>","DOI":"10.3390\/ma13020292","type":"journal-article","created":{"date-parts":[[2020,1,9]],"date-time":"2020-01-09T03:07:11Z","timestamp":1578539231000},"page":"292","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Properties of FeAlSi-X-Y Alloys (X,Y=Ni, Mo) Prepared by Mechanical Alloying and Spark Plasma Sintering"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6494-5084","authenticated-orcid":false,"given":"Filip","family":"Pr\u016f\u0161a","sequence":"first","affiliation":[{"name":"Department of Metals and Corrosion Engineering, University of Chemistry and Technology, Technick\u00e1 5, 166 28 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"Proshchenko","sequence":"additional","affiliation":[{"name":"Department of Metals and Corrosion Engineering, University of Chemistry and Technology, Technick\u00e1 5, 166 28 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"\u0160kol\u00e1kov\u00e1","sequence":"additional","affiliation":[{"name":"Department of Metals and Corrosion Engineering, University of Chemistry and Technology, Technick\u00e1 5, 166 28 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vojt\u011bch","family":"Ku\u010dera","sequence":"additional","affiliation":[{"name":"Department of Metals and Corrosion Engineering, University of Chemistry and Technology, Technick\u00e1 5, 166 28 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franti\u0161ek","family":"Laufek","sequence":"additional","affiliation":[{"name":"Institute of Physics, The Czech Academy of Sciences, Na Slovance 1999\/2, 182 00 Prague, Czech Republic"},{"name":"Czech Geological Survey, Geologick\u00e1 6, 152 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"975","DOI":"10.1016\/S1359-6462(00)00327-4","article-title":"High temperature oxidation behaviour of FeAl intermetallics\u2014Oxide scales formed in ambient atmosphere","volume":"42","author":"Xu","year":"2000","journal-title":"Scr.
