| 1 | Process Modeling for Heat Treatment: Current Status and Future Developments显示文摘Heat Treating is a critical manufacturing technology. This is particularly true in countries with large manufacturing industry including:; automotive, construction, transportation, and aerospace sectors. Technical advancement of the heat treating industry will be a critical component of the increasing need to remain competitive in this manufacturing sector on a global scale. ASM International has identified the development of process modeling and numerical simulation as a critical technology for the advancement of the heat treating process industry. In this paper, a selective overview of the current accomplishments and future needs of process modeling technologies in heat treatment will be provided. | Tatsuo Inoue, Kiyoshi Funatani and George E.

| 2 | The Trends and Tasks of Modeling and Simulation for Reduction of Heat Treatment Distortion显示文摘The development of simulation model and benchmark work have expanded in the past decade and many models and soft ware are introduced. The leading software 'Hearts’ developed by Prof Inoue[1] and several other have proved the effectiveness as the pre-production simulation work at many part of heat treatment processes[2-10]. Although, numerous other models and simulation studies dealt with many fundamental factors are reported at many conferences except very few models have not completed three dimensional computation methods, or lack of validation work to evaluate their tools exactly. In this paper, several distortion case studies will be introduced and the needs of fundamental study of distortion and internationally collaborative program on model evaluation and construction of materials database are proposed. | Kiyoshi Funatani Nihon Parkerizing Co., Ltd.Momosono-cho 4-18, Mizuho-ku, Nagoya, JAPAN | 2000 | Journal of Shanghai Jiaotong university(Science)2000，5，1： | 7 |

| 19 | Challenges to Introduce Advanced Cooling Technology by the Utilization of Plural Cooling Velocity显示文摘The control of cooling power is very important to introduce desired properties. Usually, higher the cooling rate higher the quench hardness and distortion and the optimization of cooling power is the base for good heat treatment. The change of cooling speed during quenching is one of the effective methods to balance hardness and distortion. Different form the general knowledge of the demerit of vapor blanket stage, oil with long vapor blanket stage is also one of effective methods to reduce distortion. The reduction of distortion with enough quench hardness seems to be possible by optimization of cooling condition by the help of computer simulation. The exhibition of higher core hardness than surface in through hardening steels experienced in the 'Inverse quench hardening' was introduced by Prof. Tamura and Shimizu. This mechanism is well explained by Arimoto et al, by analysis of computer simulation. In this paper, plural steps cooling methods are compared, in relation with cooling curve and heat transfer coefficient that is necessary to simulate quench results and the possibility of advanced cooling technology is discussed. | Kiyoshi Funatani | 2004 | 材料热处理学报2004，25，5： | 0 |
| 20 | Verification of Inverse Quench-Hardening Phenomena in Bearing Steel Specimens by Experiment and Computer Simulation显示文摘The appearance of lower hardness at the surface than at the core after through-hardening of steels is known as 'inverse quench-hardening.' Pioneering work was performed in the 1970s by establishing a simple test procedure where cylindrical specimens were cooled by air and brine sequentially to produce the effect. This phenomenon was described in relation to the polymer quenching and its effect to the improvement in the fatigue strength of the steel in the 1990s. The hardening mechanism in the same specimens as the pioneering work was recently examined using a finite element simulation method. However, this work has not been completed for lack of experimental quenching cooling curves for the comparisons. In this study, the same experiments using 20mm diameter cylindrical specimens as those of the pioneering work were conducted to obtain cooling curves and hardness distributions for comparing simulated results. Experimental cooling curves showed a temperature recovery as predicted by the simulation. Also the inverse quench-hardening phenomena were found in the measured and simulated hardness distributions of the specimens. | Kyozo Arimoto Chuanrong Jin Shigeyuki Tamura Kiyoshi Funatani Mamoru Tajima | 2004 | 材料热处理学报2004，25，5： | 0 |
