Effect of Ti5Si3 on wear properties of Ti3Si(Al)C2

In-situ synthesis of TiC/SiC/Ti3SiC2 composite coatings by spark plasma sintering

“…The high microhardness of the composite coating is mainly due to presence of TiC hard phase (microhardness~28 GPa). As reported by Liu et al, Ti 3 SiC 2 is a soft phase and microhardness of monolithic Ti 3 SiC 2 phase is~3.6± 0.6 GPa [29]. The presence of hard phases like TiC, TiSi, and Ti 5 Si 3 appears to increase the microhardness of the composite coatings [29].…”

Direct Extraction of Titanium Alloys/Composites from Titanium Compounds Ores in Molten CaCl₂

“…12) Many studies have been conducted to improve the hardness and wear resistance of Ti 3 SiC 2 , [13][14][15] and it was found that Ti 5 Si 3 can be used as reinforce particles for Ti 3 SiC 2 due to their similar thermal expansion coef cients. 16,17) Ti 5 Si 3 /Ti 3 SiC 2 composites exhibit higher hardness and improved wear resistance than pure Ti 3 SiC 2 . 17) In addition, TiC is one of the most suitable reinforcements for iron-based metal matrix composites (MMCs) due to its high hardness and chemical stability.…”

“…16,17) Ti 5 Si 3 /Ti 3 SiC 2 composites exhibit higher hardness and improved wear resistance than pure Ti 3 SiC 2 . 17) In addition, TiC is one of the most suitable reinforcements for iron-based metal matrix composites (MMCs) due to its high hardness and chemical stability. [18][19][20][21] MMCs have many advantages compared with the monolithic metals, and Fe-based TiC composites have also attracted a lot of attention because of their special properties, such as good machinability, excellent wear resistance and strength retained at elevated temperature.…”

“…For example, Ti 5 Si 3 , Ti 5 Si 3 /TiC and Ti 5 Si 3 /Ti 3 SiC 2 can be synthesized by using the mechanical alloying (MA), self-propagating high-temperature synthesis (SHS) and hot isostatic pressing (HIP) processes, etc. 7,17,[26][27][28][29] Fe/TiC composites can be conventionally produced through the powder metallurgy route. 30) Other methods such as the SHS, thermal plasma synthesis and eld-assisted combustion synthesis (FACS) have also been investigated for the production of Fe/TiC.…”

Combustion synthesis of Ti3Si1−Al C2 solid solutions from TiC-, SiC-, and Al4C3-containing powder compacts

“…interest for this work are Ti 3 Si 1−x Al x C 2 solid solutions which possess enhanced properties when compared with their related end members Ti 3 SiC 2 and Ti 3 AlC 2 [31][32][33][34]. By means of the in situ hot pressing/solid-liquid reaction synthesis at 1500 • C for 60 min, Ti 3 Si 1−x Al x C 2 solid solutions with a wide stoichiometric range were produced from elemental powders [31,32].…”
