and Compounds, 2017, 708: 662-670. [5] WU Yu-na, LIAO Heng-cheng, LU Chang-lue. Dynamic precipitation and recrystallization in Al-12.5wt% Si-0.6wt% Mg-0.1wt% Ti alloy during hot-rolling and their impacts...(8): 1914-1921. CHANG Jiang-yu, CHEN Song-yi, CHEN Kang-hua, ZHOU Liang, YUAN Ding-ling. Numerical simulation and experimental investigation of rolling deformation inhomogeneity of 7056 aluminum alloy......
) in several countries have become one of the most popular means of transportation owing to the high capacity and efficiency in different operation environment around the world. At the same time, more... to be continuous functions of space and time and the sum is equal to one [22]. Therefore, based on this, the E-E approach is not the first choice for the wind-snow flow, as those snow particles should......
(a), illustrating a hairline crack (marked with arrow). The formation and propagation of the hairline cracks, such as the one shown in Fig. 12(c), cause the detachment of material from the pin surface, leading... structure (marked with arrows) is observed on one side of the 5 wt.% Gr hybrid composite wear debris (Fig. 15(b)), while the other side has a smooth structure. The region marked with dotted circle in Fig. 15......
. Among all titanium alloys, Ti-6242S alloy is one of the developed near-α Ti alloys, exhibiting good combination of mechanical properties in high-temperature services (~550 °C) [11]. Studies conducted... compression test specimens taken from heat-treated material were machined with their axes perpendicular to rolling direction to 13.33 mm in diameter and 20 mm in length (in accordance to ASTM E209......
parameters is studied. One of the objectives is to optimize the FSP parameters to improve the UTS and elongation of the alloys. The other is to investigate the microstructural evolution and its influence...: one was the broken eutectic Mg2Si phase, and the other was the broken primary Mg2Si phase. The change in the primary Mg2Si particles was not obvious as the rotation speed was increased; however......
, excellent fracture toughness and good heat/corrosion resistance [1]. TC4 titanium alloy is by far the most popular one among titanium alloys [2]. However, the alloy is difficult to form into a complex part... the testing fixture and the dimensions of the specimen. Specimens used in the hot tensile test were previously machined by wire-electrode cutting. The length direction is the rolling direction......
is a novel metal forming technology to simultaneously shape and strengthen the Al-Zn-Mg-Cu alloys during one-step forming and aging treatment process [3,4]. There are many heat treatment tempers suitable... samples with the gauge length of 50 mm and thickness of 2 mm were machined along the rolling direction at the surface layer of the hot-rolled plate, and the geometry of the specimen is shown in Fig. 1......
Experimental The diffusion multiple [19,20] is a group of alloys capable of interfacial contact in their design geometry to include several diffusion couples and triples in one sample. After long-time... to guarantee the homogeneity. The alloys were cut by electrical-discharge machining. The diffusion multiple included one Ti-64 brick of 10 mm × 10 mm × 10 mm, one Ti-64-20Fe and one Ti-64-20Mo......
widely used in the aerospace and transportation industries [1-3]. These parts are usually formed, especially forming processes at elevated temperatures such as hot extrusion, rolling, and forging. The high.... The AA7022-T6 alloy samples were firstly heated to the forming temperature by the electrical resistance furnace, as each one of them was warmed to test temperature and held for 6 min for the thermal balance......
time at 37 °C. Statistical analysis was conducted by one-way analysis of variance (ANOVA), and p<0.05 was regarded as to be significant. 3 Results and discussion 3.1 Microstructure As shown... compared with pure titanium (Fig. 3). Since the deformation mode in friction welding is more complex compared to the rolling process, a large number of shear bands can be created in different directions......
