The particle size distribution, morphology, and chemical composition of the Ti6Al4V, which is one of the most common materials for biomedical implants because of its high strength to weight ratio, corrosion resistance, and its biocompatibility features, have been investigated.
The titanium alloy, Ti6Al4V, which is one of the most biocompatible materials, was used in this experiment.
The entire EBM process is conducted in a vacuum chamber which is appropriate for materials with a high affinity to oxygen [4].
Moreover, the hardness of the specimen was decreased after the compression testing for both as-built and machined samples and this can be attributed to the fact that the effect of the compression is to soften the material.

The proportion of stalks used as roughage is 28%, only about 5% of that used as fuel, industrial raw materials, and the straw.
Larger numbers of stalks used as building materials can not only handle stalks for increasing farmers' income, but also provide plenty of construction raw materials.
Experimental Materials Corn Stalks.
Corn stalks made into cement-based building materials are due to the performance of the straw itself.
In this topic, the thin layer wrapped cover treatment is applied to the two materials, the corn stalks and the pumice particles.

These lightest weight materials show great potential in aerospace, automotive and structural application.
CNT are the hottest materials in 20th century that was exposed by Iijima (1991)[7].
