摘要
采用硬度法、金相、Ｘ－ｒａｙ衍射、透射电镜和能谱分析等手段研究了Ａｇ－Ｔｉ（００５～０６１ｗｔ％Ｔｉ，下同）和Ａｇ－Ｔｉ－Ｇｄ（０５１～１３ｗｔ％Ｔｉ，００９～０４６ｗｔ％Ｇｄ，下同）合金的组织、再结晶特性和相结构。结果表明：微量Ｔｉ及Ｔｉ＋Ｇｄ加入Ａｇ中，有效细化晶粒，提高晶粒组织稳定性，再结晶温度相应提高１００～１５０℃和２５０℃；作者还确认了某些二相合金和三相合金；最后探讨了微量元素的作用机理。
The structure,recrystallization and phase composition of Ag-(0 05～0 6)Ti alloys and Ag-(0 51～1 3)Ti-(0 09～0 46)Gd alloys have been studied by the methods of the hardness,metallograph,X-ray diffraction,transmission electron microscope and energy spectrum.The resultants indicated that after adding trace Ti and Ti+Gd into Ag,the grain can be efficiently fined,the stability of grain structure is effectly advanced and the recrystallization temperatures for Ag-(0 3～0 6)Ti alloys and Ag-(0 51～1 3)Ti-(0 09～0 41)Gd alloys would be risen by 100～150℃ and 250℃ respectively.
