Shi Changxu is a famous scientist in the field of metal science and materials science. In the field of superalloy, Shi Changxu first put forward the technology of package extrusion, It opens up a new way for the production of deformed superalloys. Shi Changxu invented a method of casting superalloy for turbine blades, studied the first generation of hollow gas cooled casting nickel based superalloy turbine blades in China. Shi Changxu discovered the new rule of solidification segregation and summarized it as "low segregation alloy technology", which promoted the development of superalloys and was honored as "the father of China superalloys" by American scholars.
