surrounded by misfit dislocations. The temperature dependence of the yield strength of precipitate-containing B2-ordered NiAl was investigated by compression tests over the temperature range...; Ni2AlTi; age-hardening; mechanical property; precipitate; [全文内容正在添加中] ......
austenite grain, packet and block are 10-15 μm, 2 μm and 150 nm, respectively, so that the strength of the steel matched its toughness well. The precipitate of (Nb,Ti)(C,N) whose size is about 50 nm can restrain coarsening of the prior austenite grain through pitting austenite grain boundary. The precipitate of (Nb,Ti)C and nanometer size precipitate of NbC can be an effective barrier for dislocation......
-jiang, WANG Cai-xia, HOU Shu-fang, WANG Bo-han. Microstructure and phase precipitate behavior of Inconel 740H during aging[J]. Transactions of Nonferrous Metals Society of China, 2016, 26(6... discussed, meanwhile, the stress relaxation test was used to analyze the creep behavior of this alloy. The results show that M23C6 carbides rapidly precipitate and grow at grain boundaries until......

. The results show that with the increase of the heating temperature or the holding time, the austenite grain size increases, while the number of the second phase precipitate decreases and the size increases... increases from 1 200 ℃ to 1 250 ℃. At 1 150 ℃ and 1 200 ℃, the solid solution of fine second phase precipitate is the main reason for the significant increase of the austenite grain size during heating......
precipitate is similar to that of over-aged condition. With the retrogression time prolonged, the tensile strength of the alloy gradually decreases while the elongation ratio slightly increases. When... addition of silver which promotes the precipitation of coarse equilibrium phase.
