分析组成相对钛合金力学性能的贡献对组织设计极为重要。通过真实组织有限元模型定量分析了α<sub>p</sub>和β<sub>t</sub>中的应力和应变,并确定了他们对Ti-6Al-2Zr-1Mo-1V钛合金强度和韧性的贡献。结果表明,α<sub>p</sub>和β<sub>t</sub>中的应力呈现正态分布。β<sub>t</sub>的峰值应力和应力峰高远大于α<sub>p</sub>。然而,α<sub>p</sub>具有较大的峰值应变,β<sub>t</sub>具有较大的应变峰高。随着α<sub>p</sub>体积分数从49%降低到12%,β<sub>t</sub>对抗拉强度的贡献从59%增加到92%,对失效应变的贡献从36%增加到75%。然而,随着β<sub>t</sub>贡献的增加,合金抗拉强度增加了17%,失效应变降低了21%。研究结果定量揭示了组成相对强度和韧性的贡献,为钛合金组织设计提供了基础。 相似文献

目的：利用阴极微弧沉积技术在预处理后的TiAl合金表面制备了Al<sub>2</sub>O<sub>3</sub>陶瓷涂层,研究了涂层的生长过程和相组成。方法：采用电子扫描电镜(SEM、EDS)、电子透射电镜(TEM)、X射线衍射(XRD)等方法,对Al<sub>2</sub>O<sub>3</sub>涂层的生长过程中的微观形貌、组织成分以及晶体结构的演变进行了研究与分析。结果：TiAl合金表面阴极微弧沉积过程中,在阴极表面发生非晶态Al(OH)<sub>3</sub>的吸附、脱水烧结形成Al<sub>2</sub>O<sub>3</sub>陶瓷涂层的沉积。结论：Al<sub>2</sub>O<sub>3</sub>涂层生长分前期Ⅰ、中期Ⅱ和后期Ⅲ三个阶段,前期起弧阻挡层被击穿,涂层生长较慢、组织致密且与基体结合良好;反应中期涂层生长较快,Al(OH)<sub>3</sub>不断吸附和脱水烧结,涂层结晶度提高;反应后期涂层生长速度变缓,表层组织疏松、多孔,相组成为87.5 %的α–Al<sub>2</sub>O<sub>3</sub>和12.5 %的γ–Al<sub>2</sub>O<sub>3</sub>。 相似文献
