J. Cent. South Univ. (2021) 28: 1978-1989 DOI: https://doi.org/10.1007/s11771-021-4746-2 Annealing twin mechanism for 304 stainless steel solution treatment process JI Kai-sheng(纪开盛)1, SONG Guang... and grain orientation variation during the solution heat treatment process of the 304 stainless steel pipe were studied. It was found that after the solution heat treatment, the texture type clearly......
Strengthening of High Strength Rebars张晓刚,姚卫薰摘 要:<正> The influence of alloying elements and coolingconditions after rolling on the microstructures andmechanical properties of a series of medium carbonSi-Mn-Mo-V high-strength precision-formedrebars were investigated.It is found that steel withcombined addition of Mo and V appears to be themost......
. It is considered that hydrogen solution strengthening and V element diffusion are the main factors causing the hardness of α phase increase with the increase of hydrogen, and the formation of δ hydrides, lattice defects, hydrogen solution strengthening and Al element diffusion jointly cause the hardness of β phase increase with the increasing hydrogen. Key words: Ti6Al4V alloy; hydrogenation......
, and the maintenance of solution redox potential under an optimum range. Up to date, considerable researches on the first two terms have been summarized, while the overview of the last term has been rarely reported. Based on corresponding works in recent years, key trends and roles of solution redox potential in copper hydrometallurgy, including its definition, effect and maintenance, have been......
conditions can be adopted in this method. In this work, two electrode–clay contacts, three solution conditioners, and four anode solution supply times were used for clayey soil improvement. Based... beneficial for the transport of Ca2+, production of cementing material, and reduction of water content than that of electrode–clay (E_C) joining; through electrode–clay contact separation, the anode solution......
gradually leads to the increase of alloy softening. The mechanical properties of aged alloy are determined by precipitation strengthening and solution softening, and the suitable solution treatment... 文献标志码:A Effects of solution treatment on microstructures and mechanical properties of Al-5.8Cu-0.6Mg-0.6Ag-0.3Nd aluminum alloy TIAN Zhe1, 2, YI Dan-qing1, 2, LIU Hui-qun1, 2......
have great effect of solid solution strengthening[5-6]. Solid solution strengthened Nb alloys with V, Ta, Mo, Hf and W have been reported[7-9], and also some two-phase in-situ composites containing... properties through dispersion strengthening, solution strengthening and boundary strengthening. We know, however, that the temperature of eutectic transformation decreases as Ti with low melting point......

was investigated in air and 3.5 wt%NaCl solution. Epoxy coating as a new method was used to improve the corrosion fatigue property of the material.Results show that the fatigue limit(FL) of the coated specimens is higher than that of the uncoated specimens in3.5 wt% NaCl solution because of the strengthening and blocking functions of the epoxy coating. The FL of the coated specimens in 3.5 wt% NaCl solution......
