Its advantages of being located in the center of the Korean peninsula and proximity to convenient traffic alleys including the Namhan river facilitating the transport of materials would have been an important factor contributing to the area’s importance.
It is also thought that a variety of iron materials varying in carbon content were produced[6].
The bottoms of the furnaces excavated at archaeological sites were protected against moisture and high temperatures using beds of crushed rock, charcoal, and sand, etc., although the materials used and the order in which they were layered could vary.
As only analysis data on iron bars exists at this time, further research into intermediary materials is required.

Thus, it will decrease the possibility of scratching and breaking, and at same time protect matrix and improve the wear-resistance of material.
As some literature shown, in high V containing materials, V maximum content can reach to 15% and lowest content is not less than 2%.

The relatively systematic research on mechanical properties and structural performance of recycled aggregate concrete was conducted by many scholars at home and abroad, however the research about wall materials made with recycled concrete aggregate was less.
Currently concrete hollow block as a new-type wall material can replace the clay bricks.
Strength and other properties of recycled aggregate concrete can meet the requirements of production of recycled aggregate concrete wall materials, the production of concrete hollow blocks using recycled aggregate (known as recycled aggregate concrete hollow blocks) is reasonable, and it will have significant long-term and practical significance for energy-saving construction and wall reform.

Introduction Titanium matrix composites (TMC) have higher specific stiffness/strength, higher wear/corrosion resistance, higher anti-fatigue performance and better high-temperature properties, which are recognized as one of the new materials to replace titanium alloys.
Experimental Work Materials and Machine Tools.
The machined materials in the experiments were vol.(5-8)% TiCp/TC4 composites which were produced through vacuum self-consuming electro-arc melting and hot forging technology.

This is explained with their increased specific strength in comparison with traditional high-strength materials.
This increases the strength of the material.
