Hot Pressing Sintering

In this study, the dense bulk Cu2Se thermoelectric (TE) materials were prepared by microwave melting and hot pressing sintering. The effects of different cooling processes on the microstructure and TE properties of Cu2Se were investigated. The results showed that the Cu2Se TE material prepared by microwave synthesis had high electrical conductivity, which was about 105 S⋅ m[Formula: see text]. The annealing process can lead to grain growth of Cu2Se and the formation of micropores in the Cu2Se, which deteriorated the thermal conductivity. The Cu2Se material prepared by the microwave melting and slow cooling process had the best TE performance, and the ZT value can reach 0.68 at 700 K.

Bake Hardening Steel

A two-step rolling-annealing process has been developed to increase the <111>//ND (γ fiber) component in the recrystallization texture of a copper-bearing bake hardening steel. The two step process comprises the first rolling by a low reduction in thickness and subsequent annealing at 780°C, followed by the second rolling by a high reduction and subsequent annealing at 780°C. The first rolling process aims at seeding the γ fiber oriented grains, so that they can grow at the expense of differently oriented grains developed in the second rolling process. In this way the density of γ fiber component in the recrystallization texture of the bake hardening steel much increases compared with that in the conventional one-step rolling-annealing process.

Cold Rolled

The anisotropy in mechanical strength and electrical conductivity in Cu-Ag alloy during cold rolling were investigated. The anisotropy in tensile strength and electrical conductivity was significant with increasing Ag content in Cu-Ag alloy. The cold rolled Cu-Ag alloys with higher Ag content have filamentary structure, which is composed of elongated eutectic phase and Cu matrix. In addition, the eutectic phase in Cu-Ag alloys with higher Ag content has a strong α-fiber texture. It can be mentioned that the eutectic phase in filamentary structure is promotes the anisotropy of electrical conductivity of Cu-Ag alloys. This strong a-fiber texture of eutectic phase was decreased by annealing process (300 OC for 1h), and the anisotropy in strength and conductivity was decreased.
