Characterization of Precipitation in 7055 Aluminum Alloy by Laser Ultrasonics
نویسندگان
چکیده
After different rolling conditions, four 7055 aluminum alloy samples with precipitation sizes were measured by scanning electron microscope, transmission microscope and laser ultrasonic. The attenuation coefficients of ultrasound ultrasonic calculated in the time domain, frequency domain wavelet denoising, respectively. relationship between precipitate size coefficient was established. results show that wave is related to precipitated phase; this provides a new method for rapid non-destructive testing alloys.

15 صفحه اولThe effect of surface roughness on 1050 aluminum alloy weld profile welded by pulsed Nd:YAG laser
Surface roughness in the welding processes is one of the important parameters in the laser welded metal connections which affects laser beam absorption directly. When the laser beam is irradiated to the surface of the base metal, the surface roughness plays an important role in the amount of beam absorption and the amount of melting achieved and directly affects the penetration depth. The main ...

متن کاملIsothermal Time-Temperature-Precipitation Diagram for an Aluminum Alloy 6005A by In Situ DSC Experiments
Time-temperature-precipitation (TTP) diagrams deliver important material data, such as temperature and time ranges critical for precipitation during the quenching step of the age hardening procedure. Although the quenching step is continuous, isothermal TTP diagrams are often applied. Together with a so-called Quench Factor Analysis, they can be used to describe very different cooling paths. Ty...
متن کاملEnhancing the low cycle fatigue strength of AA6061 aluminum alloy by using the optimized combination of ECAP and precipitation hardening
In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile stress and decreased the ductility of the alloy. However, the improvement of low cycle fati...
