The effects of cold-rolling with different reduction ratios of 70%-90% on the microstructure and mechanical properties of Ti50Zr30Nb10Ta10 alloy were investigated. It was found that the β-Ti phase in this alloy was stable under cold-rolling. With the increase in reduction ratio from 70% to 90%, the microstructure of the alloys evolved from deformed dendrite structure to fiber-like structure. The alloy cold-rolled with the reduction ratio of 70% exhibited optimum mechanical properties of combined high fracture strength of 1012 MPa and plastic strain of 10.1%, which are closely correlated with the dendrite structure of the alloy. It is indicated that the proper cold-rolling is an effective way to improve the mechanical properties of the titanium alloy.

In this paper,effect of the different forging processes on the microstructure and mechanical properties of the flat flat billets of TA15 titanium alloy was investigated.The flat billiets of 80 mm×150 mm×L sizes of TA15 titanium alloy are produced by four different forging processes.Then the different microstrure and properties of the flat billiets were obtained by heat treatment of 800 °C~850 °C×1 h~4h.The results show that, adopting the first forging temperature at T1 °C、slow cooling and the second forging temperature at T2°C 、quick cooling, the primary αphases content is just 10%, and there are lots of thin aciculate phases on the base. This microstructure has both high strength at room temperature and high temperature, while the properties between the cross and lengthwise directions are just the same. So the hot processing of the first forging temperature at T1 °C、slow cooling and the second forging temperature at T2°C 、quick cooling is choosed as the ideal processing for production of aircraft frame parts.

Fe-6.5wt.%Si alloy is an excellent soft magnetic material. Due to the appearance of ordering structures, the alloy shows poor ambient temperature ductility, and can only be cold rolled by specific rolling process. The rolling process with heat treatment is complex and time consuming. Meanwhile, high-energy electropulsing shows electroplastic effect. Heat treatment effect of the high-density electropulsing on microstructure and mechanical properties were investigated. The hot rolled sheet with 1 mm in thickness could be uniformly recrystallized in 33 s at 690 oC by appropriate high density pulses and the ductility was improved in comparison to the conventional heat treatment in a furnace. After the electropulsing treatment, the hot rolled sheet could be warm rolled by 50% reduction of the thickness after one pass without edge crack.
