Al-Si matrix MMCs which are reinforced by alumina short fibers have been widely applied to piston materials [3-5].
Material and methods The short fiber reinforced MMCs used in this study were Al-Si piston alloy (Table 1) reinforced with three volume fractions of 10, 17 and 25 vol.% alumina short fibers.
This meant there was an optimal volume fraction of alumina short fibers for the Al-Si MMCs piston material.

Titanium alloy laser additive manufacturing technology integrates the latest achievements in the field of mechanical engineering, CAD / CAM, CNC technology, laser technology and materials science.
In the plane stress field, the material flow caused by indentation pressure will cause the material relaxation deformation (the material shortened in tensile stress zone, and elongated in compressive stress zone).

Introduction With the development of backfill and utilization concept for dredged materials of port engineering, soft soil foundation treatment of port engineering becomes more and more important, which has been one of key factors influencing engineering quality, construction period, and construction cost.
Construction period, material cost, labor cost, and machine-shift cost are quantitative indicators, which can be calculated actually.

Historical Background The application of nanosized materials is much older than today’s science, and dates back to ancient Egyptian, Chinese, and Roman times.
In materials science, zinc oxide is classified as a semiconductor in group II-VI, whose covalence is on the boundary between ionic and covalent semiconductors.
