systems is also very important. Aluminum and its alloys can be strengthened by precipitation strengthening heat treatment. The precipitation strengthening consists of three stages: solution heat treatment... conditions in terms of electrochemistry in relation to solution treatment, quenching and artificial aging treatment have been established in order to optimize the precipitation strengthening conditions......

Strengthening effect and mechanism......
has also been reported to form clusters within the γ matrix, and these clusters are thought to be a more potent source of strengthening than other elements in solid solution[4]. Moreover, Re as well as the other refractory metals can alter γ/γ′ lattice misfit[5]. The general characteristics of these studies are as follows: investigating on Re distribution and focusing on solution strengthening......
of the intergranular second phase also increases to 22%. Owing to the combined strengthening of grain refinement, solid solution, and dispersion, the compression strength of the Mg–Zn–Cu–Zr–Ca alloy solidified under 6 GPa is up to 520 MPa. Key words: high pressure solidification; Mg-Zn-Cu-Zr-Ca alloy; Mg2Ca particle; solution strengthening; grain refinement strengthening 1 Introduction As lightweight structural......
℃ with an extrusion ratio of 9. Grain refinement was the main strengthening mechanism utilized in both the as-cast alloy and the solution-treated alloy. Work hardening played an important role... in the sample extruded at high temperature and large extrusion ratio, but no more than 24.1 MPa. Solution strengthening was another strengthening mechanism in the extruded as-cast alloy,especially......

Origin of Insignificant Strengthening Effect of CNTs in T6-Treated CNT/6061Al CompositesKe Zhao1,2,Zhen-Yu Liu1,Bo-Lyu Xiao1,Ding-Rui Ni1,Zong-Yi Ma1,31. Shenyang National Laboratory for Materials... with friction stir processing(FSP). CNTs were dispersed after FSP and accelerated the precipitation process of the CNT/6061 Al composites. However, the strengthening effect of CNTs on the T6-treated......
