AF control

The shape memory effect of nickel originates from the phase transformation between martensite and austenite. The AF temperature (austenite transformation end temperature) is the key node, and its transformation is affected by composition and process.

  • Product Description
  • The shape memory effect of nickels originates from the phase transformation between martensite and austenite. The AF temperature (the temperature at which the austenite transformation ends) is a critical transition point, influenced by both composition and processing.
    In the medical field, controlling the AF temperature allows stents to be precisely formed at body temperature, safely supporting blood vessels. In aerospace, it ensures stable connection of components under extreme temperature fluctuations.
    AF control is primarily achieved through heat treatment. Adjusting the temperature, duration, and cooling rate can alter the alloy structure. Fine-tuning alloying elements such as cobalt and copper can also achieve precise control of the AF temperature.
