RT Journal Article SR Electronic A1 Knaislová, Anna A1 Šimůnková, Vendula A1 Novák, Pavel T1 High-temperature Oxidation of Intermetallics Based on Ti-Al-Si System JF Manufacturing Technology Journal YR 2018 VO 18 IS 2 SP 255 OP 258 DO 10.21062/ujep/87.2018/a/1213-2489/MT/18/2/255 UL https://journalmt.com/artkey/mft-201802-0015.php AB Ti-Al-Si alloys excel with their low density and good resistance against high-temperature oxidation in comparison with so far commonly used nickel alloys. Silicon in Ti-Al-Si alloys has significant positive effect on high-temperature oxidation due to increasing adhesion of oxide layer. The TiAl20Si20 alloy was evaluated as the best alloy from tested ones, because its oxide layer protected very well the basic material and TiAl20Si20 achieved good hardness after 400 hours of annealing.
