It has been found that there are some texture flaws such as large grain、badly distorted twin and streaky structure. But recrystallization grains ofaround 19μm in diameter on average are obtainable through heat treatment at300℃for 30min by air-cooling, meanwhile the twin and streaky structurethat would weaken the plasticity of alloy are eliminated; significant elementsare holding temperature、holding time、cool-down methods. Mechanicalproperties of tube are obtained, simple tension elongation ratio of arc testsample increases from 10.8% to 20.1%, elongation ratio with elastic internaldie of tube increases from 8.0% to 14.9%.

Using the perturbation method and Stroh's formula, a nonideal crack, which is mathematically sharp and the opposing crack faces still have a gap in which a stiffless dielectric fills, the two-field problem is reduced to a standard Riemann-Hilbert problem. The internal electric field distribution is obtained by solving a singular integral equation, and then the full field both inside and outside the crack is obtained and the electro-mechanical intensity factors to the first order of accuracy are given.
