Titanium alloy used in frame of sunglasses. Titanium alloys are heat treated for a number of reasons, the main ones being to increase strength by solution treatment and aging as well as to optimize special properties, such as fracture toughness, fatigue strength and high temperature creep strength.
Mill anneal, duplex anneal, and solution treatment and aging heat treatment processes for Ti-6Al-4V. Exact times and temperatures will vary by manufacturer. Ti-6Al-4V is heat treated to vary the amounts of and microstructure of and phases in the alloy. The microstructure will vary significantly depending on the exact heat treatment and method ...
Ti-6Al-2Sn-4Zr-2Mo (UNS designation R54620), also known as Ti 6-2-4-2, is a near alpha titanium alloy known for its high strength and excellent corrosion resistance. It is often used in the aerospace industry for creating high-temperature jet engines and the automotive industry to create high performance automotive valves.
Maraging steels offer good weldability, but must be aged afterward to restore the original properties to the heat affected zone. [1] When heat-treated the alloy has very little dimensional change, so it is often machined to its final dimensions. Due to the high alloy content maraging steels have a high hardenability.
Ti-6Al-7Nb (UNS designation R56700) is an alpha-beta titanium alloy first synthesized in 1977 containing 6% aluminum and 7% niobium. It features high strength and has similar properties as the cytotoxic vanadium containing alloy Ti-6Al-4V. Ti-6Al-7Nb is used as a material for hip prostheses. [1]

In addition to the alloying element nickel, the alloy contains 25 percent chromium, 20 percent cobalt, about 5.5 percent molybdenum. 1.1 percent aluminum, and 1.7 percent titanium. Various tests have shown that the material in the solution-annealed and hardened condition achieves higher hardness values and lower creep rates than, for example ...
"Cluster headaches usually last from 15 minutes to three hours and tend to occur in cycles lasting days or weeks," he said. Cluster headaches are commonly misdiagnosed as migraines.
