The Relationship Between Ln Sinh ασ 1000 T Download Scientific Diagram Download scientific diagram | the relationship between ln(ε · ) ln[sinh(ασ)]. from publication: hot deformation of the mn ni cr alloy during compression | in this paper a constitutive equation. S is the average slope of the lines in the ln[sinh(ασ)] against 1000 t plots, as shown in fig. 8. the value of ln(a) is obtained from the intercept of the ln(z) against ln[sinh(ασ)] plot.
The Relationship Between Ln Sinh ασ 1000 T Download Scientific Diagram Fig. 6 exhibits the relationship between ln ε −∂ ln[sinh( ασ )] and ∂ ln[sinh( ασ )] −∂ (1000 t ) . therefore, the mean values of n and s can be obtained from fig. 6(a) and (b. Figure 4 shows the linear relationship between ln[sinh(ασ)] vs. ln(έ), and ln[sinh(ασ)] vs. 1000 t at a strain of 0.5. by averaging the slopes of the linear fits shown in fig. 4a and b, n and temperature sensitivity parameter (t p) can be obtained. (1) ε ̇ = a 1 σ n 1 exp − q rt (2) ε ̇ = a 2 exp βσ exp − q rt (3) ε ̇ = a sinh ασ n exp − q rt where, n 0 and n are stress exponent, r is molar gas constant 8.314 j mol·k, t is absolute temperature, q is hot deformation activation energy, a 0 , a 1 , a , α , β are material related constants, and α = β n 1 . Here, an example of the plots of ln ε ̇ − ln σ, ln ε ̇ − σ, ln ε ̇ − ln sinh ασ, and ln[sinh(ασ)] − 1000 t at a strain of 0.3 are shown in fig. 7. the values of the parameters are calculated by averaging the slopes of each lines. the value of n 1 obtained from fig. 7 (a) is 5.412, β from fig. 7 (b) is 0.031, n from fig. 7.

Download scientific diagram | relationships between (a) lnε and ln[sinh(ασ)] and (b) ln[sinh(ασ)] and 1000 t. the application of natural logarithm on both sides of eq. (1) yields, lnz z lna a. The flow stress at the strain of 0.3 was used to draw the scatter diagrams of ln ε ˙ vs. lnσ and ln ε ˙ vs. σ respectively, and the data were linearly fitted, as shown in figure 5a,b. the linear relationship between ln ε ˙, lnσ, and σ is evident. the slopes of the straight lines represent the values of material constants, which were.
