In tube making by pilgering, it is possible to reduce wall thickness as well as diameter of the tube. Q factor is defined as the ratio of wall thickness reduction to diameter reduction. The value of Q can be adjusted in the manufacture of tubes by changing the conicity of the mandrel. In the case of zirconium, the single crystal is anisotropic being of hexagonal close packed structure. Poly crystalline zirconium is not anisotropic, but develops a preferred oreintation after cold work. Deformation takes place by prismatic slip and by twinning. When the Q factor is maintained high, that is, when wall thickness reduction is much more than diameter reduction, the crystals take radial positions in the wall thickenss of the tube. When the Q factor is low, the crystals take tangential positions In nuclear applications of zirconium, in the event of hydriding, the hydride forms perpendicular to the c axis of the hcp crystal. A high Q factor leads to tangential hydride platelet formation, which is acceptable. High Q factors are achieved in pilgering. A low Q factor leads to radial hydride platelets in the thickness of the tube and hence has deleterious effects. Low Q factors occur in drawing process. Hence for nuclear applications, high Q factors through pilgering are used. Balakrishna Palanki Ph.D

Q factor of low pass filter?
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
What is the Q factor in electrical and electronics engineering?
Q is the general idea of component quality, mainly in AC circuits. It is equal to reactance divided by resistance. The Q factor of an entire circuit can also be computed the same way. In general, adding resistance decreases the circuit or component Q. The "Q" factor is a empirical number to imply the acuteness of a circuit to discriminate surrounding influences and act on the Q of the circuit. The higher the Q THE SHARPER THE RESPONSE.
How do you improve Q factor?
Minimize circuit resistance.
What is meant by pilgering?
Pilgering is a metal-working process for reducing the dimensions of a metal tube. The two key components of a pilgering press (or mill) are a conical mandrel, which fits inside the tube, and ring dies which roll over the outside of the tube. This process reduces the diameter of the tube to the size of the mandrel and, at the same time, reduces the wall thickness of the tube from the action of the dies rolling over the outside of the tube along the mandrel. Pilgering is usually performed cold, i.e., the metal does not need to be heat-treated for the process to be accomplished, and it takes a very great number of tiny forming steps. This makes it highly suitable to use on precious metals, since almost no metal is lost in the process. This also is a superior metal-forming process to drawing, since it can reduce the diameter of a tube to a greater degree than drawing while the tube still remains round and retains greater tensile strength against forces such as torque and stress fracturing. Cold pilgered tubes are used for such things as lightning rods, baseball bats and golf clubs, which can survive repeated sudden large-force impacts.
In resonant circuit large q factor means?
Sharp tuning the bigger the Q the sharper the response
What is the reciprocal of the power factor?

What is Q factor of a coil?
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.

What is a scientific word for q?
Q is often used to connote "electric charge".The Q factor of tuned circuits is a measure of "quality factor". It is a measure of how well the tuned circuit selects wanted frequencies and rejects the unwanted.
