By employing such a method, 5 series of elastomers, including natural rubbers, elastomeric polyester fibers and ethylene-octene, ethylene-methyl acrylate as well as SIS triblock copolymers, were investigated with the purpose of studying elongation induced phase structure and mobility changes of the samples. For NR samples, it was demonstrated that there exists a small amount of crystals at RT even for unelongated samples. For both NR and the soft segment of PEE, with the increase of elongation ratio, the elongation-induced crystallinity increases almost linearly in a certain region of R, in accord with the increase of the lamellar thickness of the crystals; The behavior of ethylene copolymers, in terms of elongation induced morphorpholgy changes, are quite different from NR and PEE. The crystals are found to be gradually destroyed with the increase of R, with accord with the decrease of the lamellar thickness; The motional behavior of the soft segment of SIS, changes from "liquid" to "solid", in terms of 13C NMR spin-lattice relaxation.For many of the aformented samples, the dependence of 13C spin-lattice relaxtion time T1 on R are different for different groups, indicating that the changes of mobility at MHz frequency region with elongation are different for different groups.

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%.
