摘要:: TC21鈦合金是我國自主研發的一種高強高韌損傷容限型鈦合金，分別采用準β鍛造、準β鍛造+(α+β)鍛造以及β鍛造工藝對TC21鈦合金進行鍛造，采用金相顯微鏡和掃描電子顯微鏡研究了鍛造工藝對TC21鈦合金顯微組織的影響規律，以及顯微組織與力學性能之間的關系。結果表明：采用準β鍛造(Tβ+15 ℃)后，TC21鈦合金顯微組織特征為破碎的β晶粒和編織程度較好的網籃組織，并且該組織具有良好的強度塑性韌性匹配；采用準β鍛造后再進行(α+β)相區小變形，顯微組織中部分片層α相呈短棒狀分布，且網籃編織程度較差，強度與塑性與準β鍛造后相當，但斷裂韌性較差；在較高溫度(Tβ+25 ℃)進行鍛造，TC21鈦合金顯微組織中形成粗大平直的晶界α相，材料的強度、塑性和韌性均較低。

Abstract:: TC21 titanium alloy is a kind of titanium alloy with high strength and high toughness damage tolerance developed independently in China. In this paper, quasi-β forging, quasi-β forging +(α+β) forging and β forging process were used to forge TC21 titanium alloy. The influence of forging process on microstructure of TC21 titanium alloy and the relationship between microstructure and mechanical properties were studied by optical microscope (OM) and scanning electron microscope (SEM). The results showed that: after quasi-β forging (Tβ+15 ℃), the microstructure of TC21 titanium alloy was characterized by broken β grains and well-woven basket structure, which had good strength-plastic-toughness matching; after small deformation of (α+β) phase region after quasi-β forging, the α phases were distributed in short rod shape, and the weave degree of the basket was poor; the strength and plastic properties of the basket are similar to those of quasi-β forging, but the fracture toughness was poor; after high temperature (Tβ+25 ℃) forging, coarse and straight grain boundary α phase was formed, the strength, plasticity and toughness of the material were low.
