- 摘要:
- 采用选区激光熔化(Selective Laser Melting,SLM)技术成形了2024铝合金,研究了扫描间隔对显微组织及室温力学性能的影响。结果表明:扫描间隔0.12 mm时,2024铝合金显微组织细小,硬度达124 HB,抗拉强度为372 MPa,具有较高的室温力学性能。
2024 aluminum alloy was formed by selective laser melting technology, the effect of scanning interval on microstructure and mechanical properties at room temperature was studied. The results show that when the scanning interval is 0.12 mm, the microstructure of 2024 aluminum alloy is more fine, the hardness is up to 124 HB, and the tensile strength is 372 MPa.
