| Abstract: | The mechanical performance and fracture of the casting ZL108 aluminum alloys treated by rare earths and without treatment were analyzed. The treated alloys have more mechanical tenacity and higher tensile strength. The results show that the total hydrogen in alloys without RE is equivalent to the total hydrogen in the alloys treated by RE. The bind energy and fracture morphology show that RE changes the existence state of hydrogen. |
