Abstract

The structure and process design of the ZL205 Aframe casting were described

and the filling field

temperature distribution field

thermal stress and strain field during the solidification process were simulated by the FDM and FEM method.The gravity filling process of ZL205 Aframe casting was determined by the optimization of the T5 heat treatment process parameters and the location as well as size of reserved hole.The results show that the solidification sequence from inside to outside can be realized in the solidification process

and the peak value of thermal stress is 47.17 MPa.In addition

the average tensile strength

yield strength and elongation of the samples reach 510 MPa

402 MPa and 6.8%

respectively

after the T5 heat treatment

which meets the GB/T 9438-1999 technical requirements.
