; 1 INTRODUCTION The electroheat carbon film is a new functional electroheat film developed based on the electroheat coating. Due... electroheat temperature of 2000℃[10] above theoretically in a reducing atmosphere at a low voltage. Besides, HPMETCF can be divided into single planes or curved electroheat units so as to greatly extend......

Article ID: 1003-6326(2005)05-1108-05 Effects of micro-alloying with Sc and Mn on microstructure and mechanical properties of Al-Mg based alloys CHEN Xian-ming(陈显明)1, LUO Cheng-ping(罗承萍)1, PAN... of the Al-Mg based alloys. It is found that the micro-alloying can significantly enhance the tensile strength of the alloys, and eliminate the dendritic cast structure in it. Many fine, spherical......
deformation will promote cracking in the brittle alloying layer on the Cu-Cr-Zr tip surface, which in turn speeds up the tip material loss. This may also explain why there appears only one single layer... resistance spot welding zinc coated steel [J].

When the temperature T is equal to TR,the probability ω(T=TR, ΔE=0) is 1/2. But when the temperature T is higher than TR,the probability ω(T, ΔE=0) is at the vicinity of 1/2. Based......
]. Physical modeling is oriented to partial liquid flow in a cell, the flow field features around a single anode can be well represented. For better understanding of the fluid flow phenomena in a whole... recirculations were observed in the fluid. In this paper a mathematical model based on Eulerian-Lagrangian formulation, was set up to simulate the water model. Then the model was improved to predict......
