  by the electrochemical deoxidation of the Ti/Al-containing oxides precursors including TiO 2 /Al 2 O 3 mixture and titanium-rich slag/Al 2 O 3 mixture at 1000 °C and 3.8 V in molten CaCl 2 . A solid oxide membrane (SOM) tube filled with carbon-saturated liquid tin was served as inert anode, and the pressed pellet of Ti/Al-containing oxides precursors was used as cathode during the electrochemical deoxidation

  thermogravimeter and differential thermal analysis (TG–DTA) techniques even after very short milling times (4 h). The use of methanol as a hydrogen source during ball milling seems to be an inexpensive and easy way to prepare nanocrystalline and amorphous ductile metal based alloys in considerably shorter milling times and without an atmosphere of hydrogen gas.

  摘要 通过间接反应球磨 (IRBM) 制备了具有不同成分的二元 Ti-Al 系统的粉末。在研磨过程中，使用甲醇作为反应控制剂获得钛和钛-铝氢化物的纳米晶粉末。由于 Ti-Al-甲醇反应，这些氢化物化合物的形成改善了粉末的晶粒尺寸减小。即使在非常短的研磨时间（4 小时）之后，通过 X 射线衍射（XRD）、热重计和差热分析（​​TG-DTA）技术也能检测到轻金属氢化物。在球磨过程中使用甲醇作为氢源似乎是一种廉价且简单的方法，可以在相当短的球磨时间和没有氢气气氛的情况下制备纳米晶和非晶态韧性金属基合金。

  The synthesis of gamma-TiAl from elemental metals via solid-state reactive diffusion processing routes involves multiple reaction steps with the formation of various intermediate intermetallic compounds, starting with TiAl3 because this phase is favored kinetically. To understand the processes by which the TiAl3 intermediate is eliminated during synthesis of gamma-TiAl alloy via spark plasma sintering (SPS), the reaction between Ti and TiAl3 during SPS was studied with emphasis on the effects of the applied electric current and starting TiAl3 microstructure on the reaction kinetics and the underlying diffusion mechanisms. The intermediate intermetallic phases Ti3Al, TiAl and TiAl2 were formed between the Ti and TiAl3 upon SPS processing at 900 degrees C. The applied electric current did not alter the character of the phases formation in the Ti/TiAl3 system, but thermodynamic calculations suggest that the activation energy for the nucleation of TiAl2 is reduced significantly with an electric current flowing. Moreover, the kinetics of the reactions between Ti and TiAl3 were enhanced when the starting TiAl3 microstructure was refined. The electric field also had a more significant influence on the grain growth kinetics for TiAl2 and TiAl in powder blend compacts with refined microstructures. Published by Elsevier B.V.
