Abstract：

In large aluminum alloy forgings,the change of inside metallurgical defects and the strain fields have been studied by experimental and numerical simulation.It shows that rational die design and billet size can effectively prevent the defects from further enlarging.The results of numerical simulation help to accurately predict and understand the change of metallurgical defects during forging.
