镀层中只有少部分锌粉颗粒发生塑性变形，并且变形取向也无明显的规律。
Only a few zinc particles in the coating occurred plastic deformation with irregular orientation.
取向的结果，导致大量的硬段残留取向、应力软化、应力滞后和高变形，以及材料的高模量和高强度。
The orientations of polyurethanes resulted in a large number of the residual orientation , the stress softing and stress hysteresis , the permanent set , the higher modulus and strength of materials .
