of Technology2. School of Materials Science and Engineering, Southwest Petroleum University摘 要:Semi-solid powder rolling is a strip manufacturing process, which combines powder rolling with semi-solid rolling in one step to prepare high-performance metallic strips. A total of 7050 aluminum alloy strips were prepared by semi-solid powder rolling......
Creep Behaviors of DA Casting and Rolling GH4169 Superalloy () 摘要:After the billet of Casting and Rolling GH4169 alloy was directly aged (DA) treated at 720℃ and 620℃, creep behavior and deformed features of the alloy were investigated by means of the measurement of creep curves and microstructure observation. Results show that the DA Casting and Rolling GH4169 Superalloy displays a lower......

for analyzing the deformation of inclusions. ERVASTI and ST?HLBERG[11] simulated the behavior of macro- inclusions during hot rolling, and analyzed the inclusion shape for a variety of the pass reduction..., KUSABA Y. Influences on the plastic strain distribution of slab of vertical roll shape during multi-pass V-H rolling process [J]. Acta Metallurgical Sinica (English letters), 2006, 19(1): 51-56. [5......
calculation, only consuming about one- thirteenth of the CPU time, as shown in Table 1[8]. XIE et al[9] carried out a hot ring rolling simulation with the rigid visco-plastic dynamic explicit approach... existing at the ring-rolls interfaces. The defect formation as shown is in agreement with that observed by XU et al[14] and is common in an actual open pass ring rolling process without axial rolls......
