History of Nickel-Base Alloys
Beginning in World War II, "superalloy" was used to describe a group of gold developed in turbochargers and aircraft turbine engines. These alloys required performance at high temperatures. Applications of superalloys have expanded to many other areas, including aircraft and land-based gas turbines, rocket engines, chemical and petroleum plants. They are suitable for these demanding applications. The alloys are based on group VIIIB elements, and generally consist of various combinations of Fe,Ni,Co, and Cr with small amounts of W,Mo,Ta, Ti, and Al. The three main alloys are nickel, iron and cobalt based alloys. The following Xin coral Xiaobian to share with you the development of nickel-based alloys.
