The Human mind is inquisitive from the beginning of the creation. People are always interested in something new. The result of all the technologies of present civilization is the application of investigation of the human being. In all types of construction materials, the best material is metal. The main reason for this is there is no other material, which has several characteristics as metal has at a time. Different qualities of metal are the result of a metallurgical investigation, like- strength, difficulty, elasticity, malleability, specific gravity, ductility, corrosion and fatigue resistance capacity, thermal and electrical conductivity and changes of alloying characteristics. In this case, people are using various metals in various works in the modern world, based on empathized information.
The nation that is engaged in the search of related information on the metal, and the result of which is efficient in the use of industrial fields, that nation is an advance in technology.
In the present age, from the doctor’s knife-scissor used at the time of birth, including communication, roads, bridges, industries, crockeries, radio-television, computer, spacecraft, and war weapons- there is no such fields where the metal is not used. But it seems among them that, one industries production is better, durable and long lasting than other industries. The main reason of it is the lacking of metal related research and the failure of its application. The main way to reduce the production cost and make proper quality and durability, is the investigation about metal. The purpose of selecting the right metal and its long stability, it is necessary to rely on metallurgical information. Which metal should be used in a work, what step should be taken for its quality and durability, what method should be applied to give it shape, it is only possible to know through the research of metal. People always want his necessary things will be best and attractive in lower price. Every industry want to get much profit by serving best and attractive products in lower price. A wrench in our country may have seen lower qualitative than Japan. The cause is Japan is skilled enough in the metal research and they use it in the production process successfully. The present world is fast going forward through metal and metal research. So, metallurgist have to always involve in research and have to use a certain, developed and qualified metal in production in, order to maintain the quality and improvement of the production to survive in the competition of the industries involved with metal.
