Titanium 10 V-2Fe-3Al (Ti 10-2-3) coupons were produced via laser powder bed fusion and characterized. Results indicate that coupons produced by the additive manufacturing process have substantially lower high-cycle fatigue strength compared to wrought material (40 vs. 90 ksi, or 276 vs. 621 MPa at runout, respectively). Low-cycle fatigue strength of the printed coupons was also lower than wrought coupons (1000 cycles to failure at 0.75% strain for printed coupons vs 1% strain for wrought), but there was significant overlap in the data between printed and wrought. Failure analysis and optical microscopy revealed that the printed coupons showed microstructural differences when compared to wrought, such as larger grains and smaller dimples in the fracture surfaces. Computed tomography revealed defects in printed coupons. After a 500 h salt-spray, no corrosion was visible in printed Ti 10-2-3 material. At this time, Ti 10-2-3 landing gear components which are not safety critical and do not experience cyclic loading over 10,000 cycles may be considered for production via laser powder bed fusion.

钛10 V-2Fe-3Al（Ti 10-2-3）试样通过激光粉末床熔融制备并表征。结果表明，与锻造材料相比，通过增材制造工艺生产的试样具有显着较低的高周疲劳强度（跳动时分别为40 vs. 90 ksi或276 vs. 621 MPa）。印刷试样的低周疲劳强度也低于锻造试样（印刷试样在0.75％应变下为1000个循环失效，锻造应变为1％应变），但是印刷和锻造之间的数据存在明显的重叠。失效分析和光学显微镜检查显示，与锻造相比，印制的试样显示出微观结构差异，例如，断裂表面的晶粒更大，凹痕更小。计算机断层扫描显示打印的优惠券中存在缺陷。喷盐500小时后，在印刷的Ti 10-2-3材料中看不到腐蚀。此时，可以考虑通过激光粉末床熔合法生产对安全性要求不高且不会承受超过10,000次循环载荷的Ti 10-2-3起落架部件。
