Why is TI 6Al 4V so widely used?
The titanium alloy Ti-6Al-4V is widely used in joint replacement because of its good mechanical properties. This versatile material offers high fatigue resistance, good biocompatibility, and osseoconductivity.
What do the size and shape of Widmanstätten patterns indicate?
What do Widmanstätten patterns indicate about the history of iron meteorites? The patterns indicate that the molten metal cooled very slowly over millions of years, and material in the iron meteorite is found in the cooling interiors of planetesimal sized objects.
What is Eli titanium?
One of the most commonly used titanium alloys is an alpha-beta alloy containing 6% Al and 4% V. This alloy, usually referred to as Ti 6Al-4V, exhibits an excellent combination of corrosion resistance, strength and toughness.
What is the strongest titanium alloy?
Grade 4. Grade 4 titanium is the strongest pure grade titanium, but it is also the least moldable. Still, it has a good cold formability, and it has many medical and industrial uses because of its great strength, durability and weldability.
What do the size and shape of widmanstatten pattern indicate?
What kind of metal is Widmanstatten pattern made of?
They consist of a fine interleaving of kamacite and taenite bands or ribbons called lamellae. Commonly, in gaps between the lamellae, a fine-grained mixture of kamacite and taenite called plessite can be found. Widmanstätten patterns describe features in modern steels, titanium and zirconium alloys.
What does Widmanstatten mean in crystallographic terms?
The term Widmanstätten structure is also used on non-meteoritic material to indicate a structure with a geometrical pattern resulting from the formation of a new phase along certain crystallographic planes of the parent phase, such as the basketweave structure in some zirconium alloys.
Where do Widmanstatten structures occur in carbon steel?
Widmanstätten structures made from ferrite sometimes occur in carbon steel, if the carbon content is below but near the eutectoid composition (~ 0.8% carbon). This occurs as long needles of ferrite within the pearlite. Widmanstätten structures form in many other metals as well.
Which is the correct spelling for the Widmanstatten pattern?
The most common names for these figures are Widmanstätten pattern and Widmanstätten structure, however there are some spelling variations: 1 Widmanstetter (proposed by Frederick C. Leonard) 2 Widmannstätten (used for example for the Widmannstätten lunar crater) 3 Widmanstatten (Anglicized) More
