How does the addition of titanium to aluminum alloys affect their properties and strength?

Adding titanium to aluminum alloys significantly enhances their mechanical properties and strength. Titanium increases the alloy's strength, hardness, and resistance to corrosion. It also improves the alloy's creep resistance, which is crucial for high-temperature applications. The addition of titanium refines the grain structure, leading to better ductility and toughness. Moreover, titanium helps to reduce the likelihood of stress-corrosion cracking, making the alloy more reliable in aggressive environments. Overall, titanium-aluminum alloys are stronger, more durable, and have a wider range of applications than pure aluminum or simple aluminum alloys.
