1Static 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 2019Journal of Materials Science & Technology2019,35,8:3
