在过去的研究中发现 ,含钛和碳的 β+γ′合金具有比层状显微组织更细的网状显微组织。本研究揭示合金化元素中的钛有助于细化显微组织。随着钛含量的增加 ,Ni Al的 MS温度迅速降低。这一效应归因于细小显微组织的形成。在低钛含量(2 .2 at% )的情况下 ,MS温度约在 2 5 5℃以 It has been found in past studies that β and γ ’alloys containing titanium and carbon have finer mesh microstructures than layered microstructures. This study reveals that titanium in the alloying element contributes to refining the microstructure. As the titanium content increases, the temperature of Ni Al rapidly decreases. This effect is due to the formation of fine microstructures. In the case of low titanium content (2.2 at%), the MS temperature is about 2550C
