| Abstract: | Fe-4Ni-1.5Cu alloy and Fe-4Ni-1.5Cu-0.5C alloy were prepared by powder lubrication warm compaction.Results show that under the conditions of compaction pressure of 750 MPa and compaction temperature of 100℃,the Fe-4Ni-1.5Cu-0.5C alloy presents 7.18g/cm-3 sintered density,87 HRB hardness,488MPa yield strength,537 MPa ultimate tensile strength and 4.3% elongation.The addition of C into the powder can form multiphase microstructures such as pearlite and martensite,which is beneficial to enhance matrix. |
