The production of superalloys that are used in the present time is a story of the invention of advanced melting technology. Either the final product is forged or cast, the basis of superalloy’s ability is to produce the characteristics based on the suitable option and adaption of melting techniques. Superalloy melting practices are categorized as … Continue reading Melting procedures for production of superalloys
While in the beginning of 20th century, chromium was included into cobalt, nickel and iron based alloys. The received products were significantly resistant to atmospheric conditions and to oxidation at the elevated temperatures. During World war 2, some of these alloys now comprising of more alloying agents had been used as resistance wires, dental prostheses, cutlery,furnace and … Continue reading Evolution of Superalloys during second world war
Superalloys are those nickel, iron and cobalt based corrosion and heat resistant alloys that are normally employed above temperature 540oC or1000oF. Iron based nickel superalloys are an extension of stainless steel technology and normally are melted and cast to electrode and ingot shapes for final fabrication to parts. The Nickel-iron based superalloys are wrought formed to … Continue reading Oxidation and Mechanical Behavior of Super alloys
