in Fig. 7. In Fig. 7(a), the clean surface of the composites reaches passivity quickly after being exposed to the aerobic environment, forming an Al2O3 film on the surface of the composites......
by brake forming and double processed. Two identical specimens were arranged in one group, so that there were 6 groups of tests. The section dimensions were measured at the mid-length and both ends... and the increase of yield strength due to cold-forming exist in corner region, they are going in the opposite sense on instability behavior and tend to compensate each other [16]. So, the cold working......
