【摘要】：采用常規(guī)鑄造和轉(zhuǎn)棒誘導(dǎo)形核法制備ZCuSn10合金,研究制漿工藝對ZCuSn10合金半固態(tài)擠壓件顯微組織的影響,并結(jié)合最佳工藝制備法蘭件,分析法蘭件內(nèi)部組織的演變規(guī)律。結(jié)果表明,不同制漿工藝對ZCuSn10合金擠壓件顯微組織的影響不同,擠壓件內(nèi)部組織基本與漿料組織保持一致。利用轉(zhuǎn)棒轉(zhuǎn)速為500r/min制備的漿料擠壓法蘭件,可獲得固液協(xié)同流動性良好的顯微組織,試樣壓頭處散熱較快,微觀組織以固相為主;試樣中部及試樣前段均為固液兩相共存的顆粒狀或近球狀半固態(tài)顯微組織。
[Abstract]:ZCuSn10 alloy was prepared by conventional casting and rotor-induced nucleation method. The effect of pulping process on microstructure of semi-solid extruded parts of ZCuSn10 alloy was studied. The evolution of internal structure of flange was analyzed in combination with the best process. The effect of different pulping processes on the microstructure of ZCuSn10 alloy extruded parts is different. The internal structure of extruded parts is basically the same as that of slurry. The microstructures with good fluidity of solid and liquid can be obtained, the heat dissipation at the pressure head of the sample is faster, the microstructure is mainly solid phase, and the central part of the sample and the front section of the sample are both granular or near-spherical microstructures with solid and liquid phases coexisting together.
