| 1 | Static coarsening behaviour of lamellar microstructure in selective laser melted Ti–6Al–4V显示文摘Static coarsening mechanism of selective laser melted(SLMed) Ti–6Al–4V with a lamellar microstructure was established at temperatures from 700℃ to 950℃. Microstructure evolution revealed that high heat treatment temperature facilitated martensite decomposition and promoted lamellae growth. At each temperature, the growth rate decreased with increasing holding time. The static coarsening behaviour of SLMed Ti–6Al–4V can be interpreted by Lifshitz, Slyozov, and Wagner(LSW) theory. The coarsening coefficient were 0.33, 0.33–0.4, 0.4–0.5 for 700–800℃, 900℃ and 950℃, respectively. This indicated the coarsening mechanism was bulk diffusion at 700–800℃, and a combination of bulk diffusion and interface reaction at 900℃ and 950℃ conditions. | Sheng Cao Qiaodan Hu Aijun Huang Zhuoer Chen Ming Sun Jiahua Zhang Chenxi Fu Qingbo Jia Chao Voon Samuel Lim Rodney R.Boyer Yi Yang Xinhua Wu | 2019 | Journal of Materials Science & Technology2019，35，8： | 3 |
| 2 | Review of laser powder bed fusion(LPBF)fabricated Ti-6Al-4V:process,post-process treatment,microstructure,and property显示文摘Laser powder bed fusion(LPBF)is a timely important additive manufacturing technique that offers many opportunities for fabricating three-dimensional complex shaped components at a high resolution with short lead times.This technique has been extensively employed in manufacturing Ti-6Al-4V parts for aerospace and biomedical applications.However,many challenges,including poor surface quality,porosity,anisotropy in microstructure and property,and difficulty in tailoring microstructure,still exist.In this paper,we review the recent progress in post-process treatment and its influence on the microstructure evolution and material performance,including tensile,fatigue,fracture toughness,creep,and corrosion properties.The contradictions in simultaneously achieving high strength/ductility and strength/fracture toughness/creep resistance have been identified.Furthermore,research gaps in understanding the effects of the emerging bi-modal microstructure on fatigue properties and fracture toughness require further investigation. | Sheng Cao Yichao Zou Chao Voon Samuel Lim Xinhua Wu | 2021 | Light(Advanced Manufacturing)2021，2，3： | 0 |
