雙重退火溫度對高應(yīng)力水平TC11合金組織性能的影響Effect of double annealing temperature on microstructure and?mechanical properties of TC11 alloy利用光學顯微鏡(OM)、掃描電鏡(SEM)對合金微觀組織進行分析，并結(jié)合室溫力學性能測試研究了熱處理溫度對TC11鍛件微觀組織和力學性能的影響。結(jié)果表明：升高第一階段的退火溫度，等軸α數(shù)量減少，條狀α增加，從而大幅度降低合金塑性；第二階段時效溫度的升高使得等軸α相轉(zhuǎn)變?yōu)殚L條狀，增加了初生α相顆粒間距，這有利于降低次生α相缺口敏感性，從而提高材料的塑性和韌性。通過合理的雙重熱處理溫度控制，可得到強韌性最佳匹配的合金組態(tài)。
Through the detection of mechanical properties and microstructure analysis by optical microscope and SEM, the influence of variant heat treatment processing (two-stage annealing) on the mechanical properties and the microstructure of the TC11 titanium alloy large forgings was investigated. The results show that increasing the annealing temperature of the first stage is harmful to the alloy plasticity, due to reduced content of equiaxed α-phase and increased content of stripy α-phase. However, increasing secondary ageing temperature promotes the equiaxed α-phase transforming into stripy α-phase, resulting in good plasticity and toughness. The best alloy microstructure of plasticity and durability matching can be obtained by choosing double annealing temperature parameters simply and resonably.
