| Abstract: | A new type of Al-P master alloy has been developed and its modifying effect on Si phases was investigated.It is found that the Al-P master alloy has many advantages such as more convenient in adding practice,more stable ,no pollution and no reaction slag by using the Al-P master alloy.Furthermore,the primary Si can be spheroidized,the metallographic grade and quality of the pistons can be improved,and the reject ratio can be decreased when the master alloy is applied reasonably.Therefore,Al-P master alloy has a broad applicationprospect. |
