from the die cast pieces and then tested for mechanical properties. The machining of cast sample pieces is not recommended and usually cast alloys are cast into tensile-specimen shape for testing... billets. Moreover, thixocast-UST billet showed tendency to ductile fracture upon testing for tensile strength while the untreated billets showed brittle fracture with straight facets. 4......

Tensile Properties of Surface-Treated Glass Fiber Reinforced PTFE Composite with Rare Earth Elements 程先华1,薛玉君1 (1.School of Mechanical Engineering, Shanghai Jiaotong University, Shanghai 200030, China) Abstract:The optimum amount of rare earth elements (RE) for treating glass fiber surface and its effect on the tensile properties of glass fiber reinforced polytetrafluoroethylene (GF/PTFE......
electron microscopy (TEM), and tensile testing. The results show that the mechanical properties of Al-6.5Cu-0.6Mn-0.5Fe alloys decrease slightly when the Si content is below 1.0%. This can... a wire electrical discharge machining. The tensile test was carried out on an MTS CMT5105 standard testing machine, and the reported values are the averages of at least three samples. Samples......
into eight types. In this work, the inner tensile stress and the dissipation and conversion of energy of rock and soil under compression are analyzed, then the effective conversion coefficient of energy is deduced, thus the tensile failure criterion of rock and soil under compression is established. Combined with the shear strength criterion of Mohr–Coulomb, a tensile joint shear strength......

Science and Engineering, Central South University, Changsha 410083, China) Abstract: Tensile properties, stress corrosion properties and microstructures of 2099 Al-Li alloy under different aging conditions were investigated by mechanical tests and TEM. The results show that, under the under-aged condition, the tensile strength, yield strength and elongation of alloy are 453 MPa, 382 MPa and 12.5......

of welded joint remarkably, the tensile strength of alloy with Sc increases from 395 MPa to 447 MPa and the welding coefficient increases from 0.7 to 0.8 as well. The reason for the high strength... alloy; welding; Sc; microstructure; tensile properties
. These specimens were tested with a Gleeble-1500D thermal simulator testing machine. Tensile tests were conducted with the sample gauge axes parallel to the rolling direction at different temperatures (473, 523, 573...
