| Abstract: | The authors analyzed the principle of testing the mechanical properties of material bycontinuous ball indentation method,and the common material FV520 B and KMN with different statesused in compressor impeller were chosen to be tested,using continuous ball indentation method and conventional tensile testing method to determine the mechanical properties such as tensile strength and yield strength. The author summed up thefitting equation ofyield strength measured by continuous ball indentation method of FV520 B and KMN. And the feasibility of testing the remanufactured impeller mechanical properties isdemonstrated by continuous ball indentation method. |
| Keywords: | continuous ball indentation mechanical properties non-destructive testing impeller material |
