In this paper, the effect of interference fit on fatigue life of holed plate of mechanical joints was investigated experimentally. Fatigue tests were carried out on the holed specimens of Al-alloy 7075-T6 alloy. The interference fit process consists of force fitting a fastener into the hole with a negative clearance (diameter of the fastener is larger than of the hole) that produces beneficial ...

s / Journal of Veterinary Behavior 15 (2016) 78e95 94 home and during competition revealed significant differences in exhibited gaits and a significant increase in evasive mouth gaping during competition (t6 1⁄4 3.37, P < 0.05). Together, these results suggest that horses are more stressed and exercise-challenged in competition compared to home.

The effect of ultrasonic shot peening on the environmental hydrogen embrittlement behavior 7075-T6 aluminum alloy is investigated. tensile specimens were treated by for 50 s. Surface residual stress and depth under surface evaluated using an X-ray diffractometer. Then, tested in humid air dry nitrogen gas slow strain rate technique. results showed that shot-peened specimen has a superior resist...

In this study the effect of Al–5Ti–1B grain refiner on the structural characteristics and wear properties of Al–12Zn–3Mg–2.5Cu alloy was investigated. The optimum amount for Ti containing grain refiners was selected as 2 wt.%. T6 heat treatment, (i.e. heating at 460 °C for 1 h before water quenching to room temperature and then aging at 120 °C for 24 h) was applied for all specimens before wear...

Composite material is a combination of two or more materials having compositional variations and depicting properties distinctively different from those of the individual materials of the composite. A composite mixture having more than one fiber is known as hybrid composite During the past decade, considerable research effort has been directed towards the development of in situ Metal Matrices h...
