Influence of Ti addition on wear properties of Al–Si eutectic alloys

Synthesis, Characterization and Dry Sliding Wear Behavior of In-situ Formed TiAl3 Precipitate Reinforced A356 Alloy Produced by Mechanical Alloying Method

“…After 2000 m sliding distance, the lowest wear rate was obtained for 8 h synthesized samples while the highest is seen for 16 h synthesized samples. Saheb et al 43 examined the influence of Ti addition to eutectic Al-Si alloy on the wear properties of the alloy. Approximately 40 mg weight loss was recorded for the cast alloy after 2000 m sliding distance under 19.62 N load.…”

Influence of Titanium (Ti) Addition on Wear Properties of Aluminium-Silicon -Copper (Al-Si-Cu) Eutectic Alloy

“…Conversely, these alloys showed higher wear rates compared with the binary alloy due to the tendency for embrittlement and microcracking brought about by Al3Ti intermetallic particles. Heat treatment of the Ti containing alloys at 200 o C for 6 hours enhanced further their wear resistance [3]. Addition of intermetallic particles Al3Ti, TiB2, AlB2 as a grain refiner and Al4Sr modifies the nucleated silicon to fine distributed primary crystal and concealed the growth of silicon crystal within the eutectic matrix [5].…”

“…These properties led to the demand of Al-Si alloys in the automotive industry, specially for cylinder heads, cylinder blocks, pistons and valve lifters [1][2]. Al-Si alloys find common application in marine casting, such as marine propellers, high rotating parts, valves, sea water pumps parts, heat exchangers, motors cars and lorry fittings & engine parts, cylinder block and heads, cylinder liners, axles and wheel rocker arms, air conditioner compressor, break drum, automotive transmission casing manifolds and jackets, piston for internal combustion engines and etc [3,4].…”

Structural Properties and Mechanical Behavior of the 2 Step-Reinforced Al-Si/SiCp Metal Matrix Composite by Titanium-Fiber

“…The aim of this study is improvement of strength and plastic deformation of Al-based MMC by modified interface bonding between Al-Si matrix powders with SiC p as the primary-reinforcement and Ti-fiber as the second-reinforcement [23,24] as well as observation and control of relationship of phase formation behavior between Ti-rich and Al-rich corner-based effect and various sintering methods at low temperature region. Ti-fiber is expected to work efficiently for improving interface bonding in Al-Si/SiC p matrix by diffusion based on native values for mutual mixing enthalpy between Al-Ti and Si-Ti binary systems, and low thermal expansion of Ti-fiber is capable of controlling shrinkage of sintered body during the cooling process.…”
