mechanisms including grain boundaries strengthening, dispersion strengthening, solid-solution strengthening and dislocation strengthening are the dominant strengthening mechanisms. A calculation shows...,Si的固溶度很难精确确定；第二相颗粒的体积分数和平均尺寸很难精确确定；平均晶粒尺寸也可能存在一定误差. 表3 5083铝合金不同强化机制对强度的贡献和估算的总强度 Table 3 Contribution of different strengthening mechanisms and estimated total strength of 5083Al alloy......
. 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......
, which caused lattice distortion and resulted in a solid solution strengthening effect. The results of the present study showed that the solid solution strengthening effect was insufficient to compensate for the weakening of the secondary phases strengthening effect. As a result, the yield strength of the solution-treated alloy decreased dramatically compared with the as-cast alloy. Besides, due......
strengthening, the strength and hardness of tube are increased remarkably, making the application require- ments satisfied. Heated tube after enough SHT (solution heat treatment) is quenched immediately... hardening is the main strengthening mechanism in the whole process of tube bulging. The effect of solution treatment is to improve the forming capacity and ensure that the object parts have a high......
, 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......
and dislocation strengthening, the yield strength of Mo-2.0vol.%Al2O3 alloy annealed at 1200 °C is approximately 56.0% higher than that of pure Mo. The results confirm that the addition of Al2O3 particles is a promising method to improve the mechanical properties of Mo alloys. Key words: Mo-Al2O3 alloys; hydrothermal synthesis; interface; compression test; dispersion strengthening 1......
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......
