| 摘 要： | 采用Ti粉、AlV中间合金粉,通过模压和真空烧结制备了Ti6Al4V合金,并通过随后的锻造和热处理来改变其组织和性能.通过金相显微镜、X射线衍射(XRD)仪、扫描电镜(SEM)及力学性能检测等分析手段,系统研究了压制压力对Ti6Al4V烧结体密度的影响,以及试样状态(烧结态及烧结淬火态)、锻造温度、淬火温度及时效温度等工艺参数对粉末冶金Ti6Al4V合金组织和性能的影响.结果表明:通过模压和烧结可制备出相对密度达97.4%的Ti6Al4V合金;Ti6Al4V烧结态及烧结淬火态合金经过锻造后,相对密度接近100%;通过不同热处理工艺得到不同组织和性能,能获得等轴组织,其α晶粒尺寸在5μm左右.
