| Abstract: | Directionally solidified nickel- based superalloy DZ4 is a kind of very importantstructural mater- ial.Grinding burn usually occurs in the grinding process.This paper studied the grinding mechanism of this new type superalloy on the base of systematical analysis of variable characteristics of the grinding force,grinding temperature,topography of ground surface,residual stress distribution and hardness dis- tribution of surface layer,as well as morphology of surface layer from a metallographical point.The re- sults are beneficial to grinding this new type superalloy with high efficiency and high precision. |
