Modeling and Simulation of Heat Transfer in Loaded Continuous Heat Treatment Furnace () 摘要:Continuous furnaces are widely used in the heat treatment of mass-produced parts. However, the heating... based on the calculated temperature distributions and curves, especially, the fastest heated and slowest-heated temperature-distance profiles. A case study is carried out for the heat treatment......
Vacuum Furnace - Integrated "Sub zero" Treatment B.Zieger1,Hubert Schulte1 (1.SCHMETZ GmbH, Menden, Germany) 摘要:The vacuum heat treatment with overpressure gas quenching is more and more accepted... chamber and "sub zero" systems lead towards an oxidation free and low distortion vacuum heat treatment for a broad range of parts and materials. Short and energy saving processes guarantee a high......
Laser Heat Treatment on Gear Surface and Its Practical Application DAI Zhong-sen1,SU Bao-rong1,MA Chun-yin1 (1.Guangzhou Photone Technology Co. LTD, P. R. China) 摘要:Making gears with hardened..., by study, experiment and practical use, that not only has the laser heat treatment solved the difficult problems in conventional technique, but also it has great superiority. The use cases proved......
Characterization of phases in Mg-10Y-5Gd-2Zn-0.5Zr alloy processed by heat treatment WANG Qu-dong(王渠东)1, GAO Yan(高 岩)1, 2, YIN Dong-di(尹冬弟)1, CHEN Chang-jiang(陈长江)1 1. National Engineering..., XRD, SEM and EDS. The mechanisms of microstructure evolution were discussed. The results show that, after high temperature heat treatments, the Mg12ZnY phases still exist. During solution-treatment......
New Sensor Concepts for Enhancing Heat Treatment Processes and Analysis Jay I.Frankel1 (1.Mechanical, Aerospace and Biomedical Engineering Department, University of Tennessee,Knoxville, Tennessee, USA) 摘要:The need for developing accurate quenching models requires an extensive experimental database that includes surface heat flux characterization. Quantification of the quenching process permits......
1983-2004 Heat Treatment Embraces Surface Engineering Tom Bell1 (1.Department of Metallurgy and Materials, The University of Birmingham, Birmingham B15 2TT, UK) 摘要:The origins of surface... for Heat Treatment in 1971 later to include Surface Engineering has been pre-eminent in the globalisation of the rapidly developing discipline of surface engineering. The dominant effect......
Effects of solution heat treatment on corrosion resistance of 5083F Al alloy Seong-Jong KIM, Seok-Ki JANG Division of Marine Engineering, Mokpo Maritime University, Mokpo City, Jeonnam... suffer a little corrosion in the marine environment, when they run in high speed, and high flow rate, etc. Therefore, solution heat treatment was carried out to prevent corrosion. The optimal heat......
