Experiments and methods Materials Two aluminium alloys have been studied.
The cyclic conditions were different for the two materials.
Similar hour glass specimens were used for both materials (section 1*1 mm2) but in the case of Al-Li a thin (2 µm) rectangular notch, 100 µm wide and 20 µm deep, was produced in the sample using Focused Ion Beam (FIB) machining.

Lime stabilization is particularly important in highway construction for modifying the sub-grade soils, sub-base materials and base materials.
Methodology Materials The materials used for this research are natural clay soil, quicklime and water.
According to the suitability of lime stabilization for soils of different grain size and plasticity, fine-grained materials must more than 25% passing passes sieve No.200 (0.075mm) and plastic index is greater than 10.

There are several approaches for micro fabrication such as etching, electron beam, excimer laser and micro mechanical machining, but these processes are expensive, harmful to health and unable to fabricate the materials which are difficult to break metallic bonds.
The beam is made of composite materials composed of multiple visco-elastic layers and constrained layers.
