What are the challenges in manufacturing ASTM F2063 Nitinol ingots?
Manufacturing ASTM2063 nickel titanium ingot has the following challenges:
The first is the composition control, to accurately control the proportion of nickel and titanium, small composition deviation may lead to performance does not meet the standard.
The second is the melting process, nickel-titanium alloy is prone to segregation during melting. That is, the distribution of alloying elements is uneven, which will affect the overall quality and performance consistency of the spindle.
In addition, hot processing, in the process of hot processing, the temperature range should be strictly controlled. Due to the characteristics of Nitinol such as phase transition temperature, it is very sensitive to hot working temperature, and inappropriate temperature will change the microstructure of the alloy, which will affect its shape memory effect and other key properties.
