What’s up guys?!?!?!?! This is Michael with Michael Talks Metal back for the first video of 2022! Happy New Year’s everyone.
What’s new for 2022? So glad you asked! Titanium is new for Michael Talks Metal so let’s get into it! Today our video will introduce you to our topic for the next few weeks……Titanium.
Titanium’s’ attributes include:
Corrosion resistance to a wide range of environments;
Light weight when compared to iron and nickel alloys;
Higher strengths and higher temperature limits when compared to aluminum alloys.
Where do we find Titanium used?
Titanium is used for applications in aerospace that include rocket, jet engine, and structural components. Military aircraft take advantage of the high strength to weight ratio and high fracture toughness of many titanium alloys.
Chemical and petrochemical processing equipment take advantage of the excellent corrosion resistance to many acids, oxidizing environments, sea water, and chlorides.
Titanium is recognized in the ASME pressure vessel code for applications in heat exchangers, pressure vessels, and piping in corrosive environments.
Medical applications range from instruments to joint implants.
Titanium and its alloys are classified by the room temperature metallurgical structure as either alpha, beta, or alpha-beta. Commercially Pure Titanium has an alpha structure at room temperature. The structure of an alloy is dependent on the chemical composition.
Stable alpha and stable beta alloys are strengthened by forming a solid solution with their alloying elements. Alpha-beta alloys are also strengthened in part by forming a solid solution and also from solution treating and aging their mixed structure.
The normal alpha structure for pure titanium at room temperature becomes beta at what is termed the “transus temperature” on heating. Some alloying element additions can result in a stable beta structure. Alloys with a mixed structure of alpha and beta also have a transus temperature where the structure becomes all beta.. We will explore several of the more commercially important alloys in some detail in our next videos.
The density of titanium at point 163 lbs per cubic inch is between steel at point 283 lbs per cubic inch and aluminum at .098 lbs per cubic inch.
So far, everything we have said should make titanium a very popular material to use. Why don’t we see it used more often?
Unfortunately it is also very costly to produce compared to other more common metals which tends to limit its application to those where the higher cost is justified.
Titanium alloys are found in a variety of AMS , MIL, ASTM, and ASME specifications
So stay tuned to the channel for more about titanium and titanium alloys………….. and as we always say…. Check the Specs… Twice or perhaps even Thrice
