. Thin-walled rods, structural mechanics[M]. Beijing: China Architecture & Building Press, 2006: 137-145. [20] 陈伯真, 胡毓仁. 薄壁结构力学[M]. 上海: 上海交通大学出版社, 1998: 179-190.CHEN Bo-zhen, HU Yu-ren. Thin-walled......
weighed for each alloy and put in a quartz tube. The specimen was placed in a furnace and melted in the protection of pure argon atmosphere at 500 ℃ for several hours and then cast into rods. Cu foils (90......
higher than the melting point of the alloy (about 1700 K). The alloy rods prepared by conventional casting had a size of 50 mm in diameter and 300 mm in length. Some of them were investigated......
that of the original billet. The direct extrusion of rods and solid shapes is the simplest production method in use for high production rate and accuracy. Extrusion technology is developing rapidly to meet......
of antimicrobial polycaprolactonesilica composite films with nanosilver rods and triclosan using roll-milling method [J]. Polym Adv Technol, 2011, 22: 232-236. [5] BALAGNA C, M, VERNE E, CANUTO R A, G......
at 773 K for 3 h using argon gas as inert atmosphere to avoid excessive grain growth. Sintered billets were soaked at 723 K for 4 h before extrusion and hot extrusion to produce rods of 12 mm......
, and they lay on the plane in a parallel way, following [0001]α direction. The β′1 phases with hexagonal structure in Mg-Zn-RE alloy [12] usually form as rods with its long axis parallel... of the rods; r0 is the core radius of dislocations. Equation (1) indicates that the effective planar inter-precipitates space λ plays a quite important role in strengthening the alloy......
]. As a result, the alloy has to be deformed at elevated temperature during the rods, pipes, and wire production. Hot working conditions need high-level equipment and complex processes. Moreover......
were heated to 450 °C for 60 min. Then the ingots were hot extruded into rods with the diameter of 16 mm at 450 °C with a ratio of 25:1. Extrusion was conducted under a controlled constant force......
atmosphere. The samples were machined to rods with different diameters (1, 3 and 6 mm) and 100 mm in length by a spark machining. The Bridgman type apparatus was employed to produce the directionally......
