EFFECT OF COLD WORK
Cold working Cr13Al4 leads to a rapid increase in yield and tensile strength and an accompanying loss of ductility. With 10% cold reduction,
elongation falls below 10% and yield strength approaches 100 ksi. (690 MPa).
The work hardening rate of Cr13Al4 is below that of carbon steel and austenitic stainless alloys. The n-Value or work hardening coefficient
(measured between 10% strain and the ultimate strength) typically falls in the range of 0.145 - 0.170.
