1. What is the main deformation mechanism of industrial pure titanium under the action of static war load?
The main deformation mechanism is slip. With the progress of plastic deformation, a large number of slip zones appear constantly, the grain and ulrichite are stretched and twisted, and the cracking occurs when the plastic deformation exceeds a certain limit. Under complex stress conditions, shear slip is dominant, that is, the slip is mainly carried out along two sets of planes 45° with the tens
Commonly used seven steel naming rules
Commonly used seven steel naming rules
Steel is a general term for iron-carbon alloys with carbon content between 0.02% and 2.11% by mass percentage. In actual production, steel often contains different alloying elements according to different uses, such as: manganese, nickel, vanadium and so on. Today, steel is one of the most used materials in the world because of its low price and reliable properties.
