Tungsten fiber reinforced Cu82Al10Fe4Ni4 composites were fabricated by penetrating casting method . Mechanical properties and fracture characteristic s of the composites were discuss ed by t ensile test and bending test . T he microstructure and fracture characteristic w ere investigated by Transmission electron microscopy(TEM) and Scanning electron microscopy(SEM). Microstructure observation of Wf/Cu82Al10Fe4Ni4 composites revealed that a small amount of tungsten diffused into the Fe Ni solid solution precipitated on the surface of tungsten fibers. The interface of the composite remained good after tensile test and bending test. The experimental results show ed that the interface between tungsten fibers and matrix alloy was compact, and the interface exhibited high strength under pull and bending force . The composites occurred brittle fracture in tensile test, and tensile strength was 1300Mpa. The composites also occurred brittle fracture in bending test, and bending strength was 1540Mpa..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
