Results indicate that when the strain rate is 1200 s-1, the twin number of samples in different orientation increases with plastic strain increasing; when the strain rate increases to 2800 s-1, the σ-ε curves have no obvious charges as the angle is 0o and 45o, compared with that at 1200 s-1; however the σ-ε curves vary from concave to convex when the angle is 90o, because thermal softening has occurred with increasing plastic strain, which results in the number of twin decreasing, and smaller strain hardening

It is major work to present the tectonic time duration system of the strain rate method, which is an original exploration.(1) Principle: Its basis is the stress and strain rule depending on strain capacity in steady-state stress field, but not the radioactive decay law depending on radiation dose in invariable radiation field. This can be simplified as a process of differential stress-strain rate-strain capacity-time duration calculating.

The stress-strain curves of Cu-Zn-Al alloys at different temperatures have been plotted on the tensile machine with the aid of electrometry. The main results were as follows: 1. When specimens were deformed within the range of M_s and M_d, the critical stress for inducing martensitic transformation increased with the temperature, and there existed a linear relationship between them. 2. When specimens were deformed above Af, complete pseudoelasticity might be obtained theoretically, which might be damaged, h...

The results show that dynamic softening is easy to occur in these ingots and flow stress becomes steady finally; the material constants of hot deformation are procedural parameters that stress-level coefficient α, strain rate sensibility exponent m and deformation activation energy Q are all increased with strain increasing, while stress exponent n is decreased gradually; the values α and m of the alloy homogenized are the biggest and the value n is the smallest, dynamic softening effect of the alloy is the most obvious, which can deform evenly; influence of strain on the value Q of the alloy homogenized is a little and the average value of Q is only 176.5kJ/mol, so the alloy is easy to deform; the alloy matrix shows the regular recrystallization grains when the strain is 50%; dislocation cell structure re-formed in the grains with increase of strain.
