Bainitic transformation at low transformation temperatures leads to a microstructure involving fine plates of bainitic ferrite and thin films of retained austenite. This microstructure has shown ultimate tensile strength of about 2.2 GPa, noticeable uniform elongation in the range of 5 to 30%, hardness values of about 600 to 670 HV and impact toughness in the range of 30 to 40 MPa m1/2. With ca...

In this paper, the walking capturing system socalled Simi Motion from Germany and the planta-pressure analyzing system so-called Footscan from Belguim are introduced. The above-mentioned systems make quantitative descriptions of all cases such as walking motions and plantar mechanical characteristics etc., and do a theoretical analysis of the relationship between swaying upper-limb and plantar ...

We propose a system that transports oocytes and measures their mechanical characteristics in an open environment using a robot integrated microfluidic chip (chip). The cells are transported through a micropillar array in the chip, and their characteristics are measured by a mechanical probe and a force sensor. Because the chip has an open microchannel, important cells such as oocytes are easily...

In the present research work physical, mechanical and tribological behavior of Aluminum (Al) alloy LM13 reinforced with Nano-sized Titanium Dioxide (TiO2) particulates were fabricated, mechanical and tribological properties were investigated. The amount of nano TiO2 particulates in the composite was added from 0.5% to 2% in 0.5 weight percent (wt %) increments. The Al-LM13-TiO2 Metal Matrix Com...

In this paper we utilize Support Vector Machines to predict the degradation of the mechanical properties, due to surface corrosion, of the Al 2024-T3 aluminum alloy used in the aircraft industry. Precorroded surfaces from Al 2024-T3 tensile specimens for various exposure times to EXCO solution were scanned and analyzed using image processing techniques. The generated pitting morphology and indi...

Based on the deep in situ mining environments with ?three high?, a triaxial compression experiment of water-saturated sandstone under conditions 150?C, 110 MPa confining stress and 105 pore water was carried out. The results show that creep deformation stage produces surge acoustic emission energy when radial changes from expansion to rapid compression, is sheared by single crack it damaged. Fr...
