The modern instrument manufacturing has many features,such as high technologies,multiple varieties and small quantities. Aiming at those features,an instrumentation flexible developing system (IFDS) is presented. It constitutes a kind of opening,compatible,extensible and upgradeable flexible developing system,and it will offer a kind of technology equipment for the research and development of new modern instrument products. Its flexible mechanism is able to be suited for different and special requirements of many instrument systems,and its system integrated mechanism is able to adapt to common technological features of most instrument systems. It is IFDS that makes it easy to accomplish a quick system integration of instrument products. IFDS solves key technological problems related to modern instruments development,develops multiple systems for modern instrument development and accomplishes rapid development of series of new products.
Microstructure and properties of nickel-based powder metallurgy (PM) superalloy were presented. Effects of nonmetallic inclusions and heat treatment on microstructure and properties were discussed. Development tendency of microstructure and properties of PM superalloy was presented.
