especially for welding of stainless steels‚ aluminum and magnesium. In stainless steel industry‚ TIG welding has an important role on joining thin sheets‚ tubes and pipes. Depending on this important role‚ the mechanical behaviours of TIG welded joints and criteria affecting these behaviours are the main cared subjects in industry to obtain products with less failure and use them for longer service times. Mechanical behaviours of TIG welded joints in stainless steels are also the main subject of the

However‚ steel companies were focused on making profit by rising the steel prices. President Kennedy was completely against their decision. He believed in stable prices and wages. After steel companies raised the steel price‚ President John F. Kennedy held a news conference. He wanted to alert the society about the destruction that could be occurred from increasing the steel prices

discovered. This microstructure was named by Bian’s colleageus at the United States Steel Corportion. At first microstructure of martensite and bainite seem similar‚ which had many aspects on their transformation of mechanisms. Microstructure of bainite seems to be darker than the mastenisite under a microscope. The reason behind bainite structure became useful was because of its hardness. There are few Heat treatments that steel can be tested by such as Annealing‚ quenching Harderning‚ and Normalizing.

Steel and heat treatment MILD STEEL Mild steel is also called plain carbon steel. It is the most common type of steel and it price is pretty low. Its composition is around about 0.05%-0.29% carbon content. Mild steel has a relatively low tensile strength but the surface can be hardened through carburizing. It is mostly used where large amounts of steel needs to be formed eg structural steel MEDIUM CARBON STEEL Medium carbon steel has great wear resistance and is used for forged automotive

Guns‚ Germs‚ and Steel: The Fates of Human Societies‚ by Jared Diamond‚ attempts to explain why history progressed differently for people from various geographical regions. Diamond introduces his book by pointing out that history followed different courses for different people because of differences among peoples’ environments‚ not because of biological differences among people themselves. Through his convincing explanation for how civilizations were created and evolved throughout the course of history

GUNS‚ GERMS‚ AND STEEL ESSAY Jared Diamond’s novel‚ Guns‚ Germs‚ and Steel is a speculation about how and why the Europeans ended up being the main power in earlier times and conquered so much of the world. Diamond wonders how the Europeans could have so much power and advanced technology while the rest of the world was still hunting and gathering. Although Diamond is not the first to speculate on this complicated subject‚ his answer is revolutionary. People have attributed Europe’s overwhelming
