A flying car which is also known   to all as a aircraft in street and people can take tour for a short duration or long duration. In whole world or Automobile sector one can see two types of motor one is auto and another is manual, which is more prefer by yourself. Most of the driver in aircraft prefer automated motor. In everyday many company and many scientist try to make a car which is continue or drive in air and street but they are failed to manage it   for a long duration. Glenn Curtiss who is chief of Wright brother designed aircraft in world first time. But it is try to jumped and it is successfully jumped and can not fly. After than all scientist do not stop working in automobile sector for trying to make a aircraft. Waldo Waterman first make the aircraft in 1910. In 1937 firstly go to air with his car Waterman Arrowbile which take attention from all people and amazing to all. In 1940 Jess Dixon fly his car in sky air by using automobile. But some unexpected scenery we s

Powder metallurgy techniques are used for the production of refractory metals, composite metals and porous metals and metal nonmetlas combinations and more efficient production method for certain parts.The high melting points of refractory metals make it impossible to use the conventional melting and casting techniques. The use of powder method for the manufacture of tungsten filament was described at the beginning of this chapter. This techniques only for the practical method of producing molybdenum, tantalum and others metals of the same group.  One of the outstanding uses of powder metallurgy is the combination of hard metals in th metallic matrix, which serves as the basis for cemented carbide products. In the production of cemented carbides in cutting tools, a suitable mixtures of the carbides of tungsten, tantalum and titanium with cobalt as a binder is compacted and presintered. In this condition metal can be cut, machined and ground to the final shape. The compact is th

                       Cast iron which is mainly contain carbon and iron as like as a steel. In a cast iron amount of carbon is 2 to 6.67 %. In iron-iron carbide schematic figure or diagram we find carbon amount is larger than which is needed to eutectic temperature. When in a cast irons carbon is used more these types of cast iron is brittle, for this reason when cast iron produce in commercially carbon used is a less amount such as 2 to 4 %. For rigidity of cast iron it’s   malleable is low and it can not be easily reeled   at room temperature and easily one from to another from for uses various purpose. For giving various shape of cast irons people use casting process   which melt cast iron at high temperature.   And finally for smooth surface it machined.   Cast iron is cheap and availability is high, one can do properly heat treatment,   control is better in foundry shop, alloy can produce properly.   In metallurgy cast iron classified of four types   in physically such as
