Reduction and removal of martensite stabilization in Cu-Zn-Al-Mn-Zr shape memory alloys

Abstract

The excellent fit obtained in the SSS article for low-carbon steel and CP titanium recrystallization data using SSS Eq.[5] also supports the validity of the overall SSS approach, at least for these two materials.One may also compare the EB analytical result (their Eq. [4]) to the staircase calculation based on the isothermal Avrami equation. The EB expression, however, contains a constant related to the number of nuclei and whose value is therefore not easily determined. Nevertheless, if the value of the constant in the EB relations is determined by ''forcing'' the value of X(T) to agree with that from the staircase calculation for a specific temperature, then the SSS and EB results can be compared. This was done for the case illustrated in Figure 1. It was found that the curves from the two analytical expressions were nearly identical when the EB result was forced to fit the staircase-calculation at X ϭ 0.50. REFERENCES1. V.

Prediction of Thermodynamic Equilibrium Temperature of Cu-Based Shape-Memory Smart Materials

“…Tables I and II are constructed from a detailed data pool gleaned from the literature. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Tables I and II give the inputs and outputs of the GP. The inputs are the elements to produce the alloy and the thermal treatments that are applied to the alloy.…”
