WebJul 18, 2003 · The impact of 11 alloying elements, namely, Mg, Ti, In, Sn, Al, Ag, Co, Nb, and B, at two nominal concentrations of 1 and 3 at. %, and Ir and W, at only a nominal concentration of 3 at. %, on the resistivity and grain structure of copper was investigated. The films were electron beam evaporated onto thermally oxidized Si wafers and had … WebApr 30, 2006 · The austenite grain growth occurred during continuous heating in a niobium microalloyed steel has been investigated in this work. The effect of temperature and heating rate on the grain size is studied. The free grain coarsening temperature is determined as a function of the heating rate. It is found that unpinning by precipitates occurs around 40 …

WebMicrostructure of hot-pressed Al2O3/Cu composites with a different temperature for atmosphere switching from H2 to Ar has been studied. When the composite atmosphere was switched at 1100°C it lead to a more homogeneous microstructure and the highest fracture strength with smaller deviation than when the atmosphere was switched at 1450°C. WebThis work has studied the influence of different Ti and N compositions on hot deformation strength by determining the peak stress of flow curves and the activation energy (dynamic recrystallisation). It has also assessed their influence on static recrystallisation by means of the statically recrystallised fraction versus time and the activation energy. onslow model railroaders

WebJun 4, 1998 · A review is given of Clarence Zener’s impact on physical metallurgy, based upon his famous paper on the kinetics of the decomposition of austenite. He demonstrated how basic physical principles could be applied to explain the general features of this complicated reaction. However, his models were general and many of them have been … WebMay 1, 2010 · ``Introduction to Grains, Phases, and Interfaces—an Interpretation of Microstructure,'' Trans.
