TiPolar is the fastest microtexture evaluation tool available to any sector. It marks a paradigm shift in microstructure measurement and texture mapping. TiPolar faster than its predecessor technology (EBSD). By making use of a light source, rather than an electron beam, there is no need for a vacuum chamber. This has enormous benefits: sample size is no longer constrained by the size of your vacuum chamber, and overhead cost and maintenance costs drop substantially. TiPolar is faster, has fewer constraints, and is only a fraction of the cost of its competition.
TiPolar was forged out of necessity. Microtexture
is a feature of metals, specifically titanium, that
has only been deeply considered in the last 20
years. Historically, the study of microtexture
remained mostly academic because there was little
industrial interest. In recent years, that has all
changed. In September 2017, an Airbus A380 had a
catastrophic failure of one of its fan disks
constructed of Ti-6Al-4V. Titanium is used heavily
in aircraft due to its favorable combination of low
density, high strength, and capacity to withstand
high temperatures. The reason the fan disk failed was to do with an unfavorable microtextural feature. The aerospace industry has extremely strict regulations on inspection and this disk, like all others, was inspected and passed. This is largely due to a lack of inspection techniques that consider microtexture, thus, TiPolar was born.
TiPolar is the first economically viable solution to a comprehensive measurment of microstructure and microtexture that will allow for microtextural standards to be developed and enforced on aerospace grade metals. Prior to TiPolar, the only way to quantify microtexture for qualification was EBSD. While EBSD is a mature technology, it can not operate over a large enough area of material to reprensentatively measure microtexture. EBSD was excellent for features that may be 10s of μm, but microtexture can be several inches in size. TiPolar combines high speed with an unconstrained sample size that will propagate microtextural evaluation on the necessary scale.
