Size effect is of great importance in micro forming processes. In this paper, micro cylinder compression was conducted to investigate the deformation behavior of bulk metallic glasses (BMGs) in supercooled liquid region with different deformation variables including sample size, temperature and strain rate. It was found that the elastic and plastic behaviors of BMGs have a strong dependence on ...

Nano-TiO2 (NT) and nano-SiO2 (NS) were separately added in the cement paste to investigate the rheological property of fresh mixtures and mechanical strength in hardened state. The effects of different dosages and types of nano-particles on the properties of cement paste were studied. The results indicated that the rheological behavior of the fresh cement paste coincides with the Modified Bingh...

For the development of new orthodontic elastic material, 1-butanol was added to PEMA-TA/HX resin. In the present study, basic experiments to reveal the mechanical properties of the materials were conducted. FT-IR spectroscopy showed that addition of 1-butanol did not cause any chemical changes to the PEMA-TA/HX resin. After addition of 1-butanol to PEMA-TA/HX resin, the modulus of elasticity, i...

Vascular casts were made by injection of low-viscosity plastic in eight Wistar-Kyoto rats, and the posterior half of the ocular wall was observed using the semiultrathin section method. Veins which connect with the capillaries of the posterior choroid include a venous system independent of the cortex vein and running parallel to the long and short posterior ciliary arteries. The veins flow into...

This study designed the effective fluid loss agents for controlling loss. Various polymers have been used as additives using natural polymer from cassava starch. Bulky Cassava was cleaned with water and it grounded, filtered, dried, sieved to obtain suitable starch additive size. filtration mud cake test carried out under Low Pressure Temperature (LPLT) apparatus. The sample separated accommoda...

The flexographic printing is the fastest growing printing technique nowadays [1]. The principal advantages of flexography are reflected in the markets where it is most often used. The advantages of flexographic printing are low cost and short circle time, precise ink transfer with minimum on-press adjustments, and ability to print one layer and laminate another layer over it in a continuous pro...
