燒結(jié)溫度對Micro-FAST制備TC4鈦合金的影響Effects of sintering temperature on preparation of TC4 titanium alloy during Micro-FAST

采用多物理場活化燒結(jié)微成形技術(shù)(Micro-FAST)快速制備TC4微型圓柱，研究燒結(jié)溫度對TC4微型圓柱的致密化過程及力學(xué)性能的影響。研究發(fā)現(xiàn)，Micro-FAST技術(shù)可在5 min內(nèi)實(shí)現(xiàn)TC4的快速成形，在900~1200 ℃的燒結(jié)溫度區(qū)間均可獲得相對密度大于97%的微型圓柱件，其顯微組織由條狀α相和β相組成，組織分布均勻、晶粒細(xì)小。當(dāng)燒結(jié)溫度為1000 ℃時(shí)，硬度達(dá)到最大值380.3HV0.5，較傳統(tǒng)方法制備的TC4零件硬度提高10%。隨著燒結(jié)溫度的提高，燒結(jié)體中出現(xiàn)魏氏組織，合金的韌性逐漸降低。

The rapid preparation of TC4 micro-cylinder was realized by micro-forming fields activated sintering technology (Micro-FAST). The effect of sintering temperature on the densification process and mechanical properties of TC4 micro cylinders was studied. The results show that Micro-FAST can realize the rapid forming of TC4 micro cylinder parts with relative density greater than 97% at the sintering temperatures of 900-1200℃ in 5 min. The microstructure is composed of strip α phase and β phase with the uniform distribution of the organization and fine grain. The TC4 alloy prepared by Micro-FAST has a maximum hardness of 380.3HV0.5 at the sintering temperature of 1000 ℃, which is 10% higher than that of TC4 parts prepared by traditional method. With increasing in sintering temperature, the sample is observed to appear the Widmanststten structure, the toughness of the alloy gradually reduces.
