Design, Materials and Processing for the Summer Olympic Torches *ZHANG Jian Bin1, 2, a, YU Dong Mei1, b, YIN Xiao Qiang1 and JIA Jian Gang1 1State Key Laboratory of Gansu Advanced Non-ferrous Metal Materials, Lanzhou University of Technology, Lanzhou 730050, China 2Key Laboratory of Non-ferrous Metal Alloys and Processing of Ministry of Education, Lanzhou University of Technology, Lanzhou 730050, China ajbzhangjb@gmail.com, bbjyudongmei@gmail.com (*Corresponding author) Keywords: Olympic torch, design, materials, processing Abstract: Olympic torches are the fantastic combination of successful design, appropriate materials and optimum processing which are the basic concept concepts in the major of Materials science and engineering.
The Olympic torch is a hand-held torch, which is the carrier approved by the International Olympic Committee to pass the Olympic flame from Olympia in Greece to the host city of the Olympic Stadium, and the significant legacy of the Olympic Movement (refer with: Fig. 1).
The International Olympic Committee has always attached great importance to the design, material selection and processing of the Olympic torches and each appearance of Summer Olympic torch becomes the focus of the entire world.
For example, turbine blades (refer with: Fig. 3) used in jet engines usually consist of the matrix material, the metal coating material and the thermal barrier ceramic coating.

Send the intermediate frequency signal filtered by outside ceramic filter into the second mixer, and then mix the second oscillator.
Finally send the signal filtered by external 455kHz ceramic filter into limiting amplifier and frequency discriminator[1,2].

Effect of Hot-Forging on NiTi Shape Memory Alloy Fibers Reinforced Mg Alloy Composite Qi Guoa , Gang Lib , Renjian Tangc, Biao Yan d 1 School of Materials Science and Engineering, Tongji University, 200092 Shanghai, China a guo1022@hotmail.com, b ligfriday@yahoo.com, ctrj95866@sina.com, d yanbiao@vip.sina.com Keywords: NiTi shape memory alloy fiber, Mg alloy composite, hot-forging Abstract.
Though Mg can wet many ceramic reinforcements, interfacial reaction is always serious.
Especially, the tensile strength as high as 247MPa is much higher than that of composite fabricated with the pulsed current hot pressing process, and an elongation of 7.5% is better than that of the composite reinforced with ceramic materials.
