Superalloys

Superalloys are rightly named due to their extraordinary mechanical properties and oxidation resistance at elevated temperatures. These alloys find application at most demanding service conditions like the hottest section of  jet turbine engines, space shuttle engines etc. Some superalloys operate in applications that go as high as 90% of their melting point while maintaining its high temperature properties. Superalloys consist of three groups of alloys namely nickel based, cobalt based and iron-nickel based. Base metals are extensively alloyed to achieve its superior properties. Applications Superalloys display extraordinary resistance to mechanical and chemical degradation at temperatures close to their melting points.

Titanium; An Overview of

Titanium (Ti) and titanium alloys have made significant progress in finding industrial use in the previous century due to some key advantages over other common industrial metals. Key benefits of titanium alloys over iron based and aluminum based alloys are its strength to weight ratio (Ti is roughly 60% of regular steel weight),  outstanding combination of mechanical properties (from room temperature to  elevated temperatures) and remarkable corrosion resistance.                 The major challenge of Ti manufacturing is its high reactivity with gases present in atmosphere specially at elevated temperature causing immature failure and difficulty in fabrication. Consequently, manufacturing cost of Titanium
