107年5月3日(星期四)專題演講
演講時間：107年 5月3日(星期四)下午14:30~16:00
地點：機電大樓演講廳(工EN 2028)
姓名：黃冠榮 博士後研究員
服務單位：國家理論科學研究中心物理組
主要學歷：國立臺灣大學物理系理論物理組博士
學術專長及研究領域
1. Modeling of Structural Analysis
2. Statistical Modeling of Material Processing and Properties
3. Theoretical Modeling of Biophysics and Bio-evolution
演講題目：Processing Modeling of Surface Mechanical Attrition Treatment and Its
Application
Surface mechanical attrition treatment (SMAT) introduced by Prof. J. Lu of City University of Hong Kong is widely used to improve the surface microstructure and properties of materials, such as the hardness and wear loss of commercial 304 and 316 stainless steel. In general, this technique is better than the traditional shot peening processing. In this talk, I am going to present how to optimize the processing parameters of SMAT in order to achieve the refined structure with attractive mechanical properties of 304 stainless steel using the combination of statistical modeling and experiments. On the other hand, the SMAT has been further extended to the thin film coating on sample surface, and it is called the ultrasonic mechanical coating and armoring (UMCA), proposed by Dr. Komarov. This talk will mention how to apply statistical modeling to optimize the thermal dissipation of Al heat sink through the processing of UMCA. The principles of experiments and modeling of SMAT and UMCA processing will be simply introduced in this talk.
