Solids may be categorized broadly into crystalline and amorphous solids. 2. The formation of stable nuclei in the melt (nucleation) 3. The growth of nuclei into crystals 4. The formation of a grain structure 5. The solidification of metals and alloys is an important industrial process since most metals are melted and then cast into a semifinished or finished shape.6. Columnar grains are long, thin, coarse grains created when a metal solidifies rather slowly in the presence of a steep temperature gradient.7. Ferrite is the interstitial solid solution of carbon in iron. 8. Austenite is the interstitial solid solution of carbon in iron.9. Plastic deformation is due to the motion of a large number of dislocations.10. Dislocations allow deformation at much lower stress than in a perfect crystal.11. Each heat treatment process needs heating, preserving and cooling. 12. The heating speed, highest heating temperature, preserving time and cooling speed are the four factors of heat treatment process.13. Flame hardening consists of hardening the surface of the component by heating it above the transformation temperature using a high temperature flame or high velocity combustion products and then quenching it in water or oil.14. Plain-carbon steels have low corrosion and oxidation resistance.15. Medium-carbon plain-carbon steels must be quenched rapidly to obtain a fully martensitic structure. 16. Plain-carbon steels have poor impact resistance at low temperatures.17. In this book low-alloy steels containing from about 1 to 4 percent of alloying elements will be considered alloy steels. 18. The way in which alloy elements distribute themselves in carbon steels depends primarily on the compound- and carbide-forming tendencies of each element. 19. The carbide-forming elements such as tungsten, molybdenum, and titanium raise the eutectoid temperature of the Fe-Fe3C phase diagram to higher values and reduce the austenitic phase field. These elements are called ferrite-stabilizing elements.20. Cast irons have often significant amounts of silicon, as well as smaller amounts of other elements.21. The range of carbon content gives cast irons a high fluidity. Also the materials when solidifying show no significant volume contraction.22. However, if there is very slow cooling, the Cm is not stable and graphite flakes can form.23. Moderate and slow cooling rate favor the formation of graphite. The solidification rate also affects the type of matrix formed in gray cast iron. 24. Moderate cooling rates favor the formation of a pearlitic matrix, whereas slow cooling rates favor a ferritic matrix.25. Gray cast iron is formed when the carbon in the alloy exceeds the amount that can dissolve in the austenite and precipitates as graphite flakes.26. Since silicon is a graphite stabilizing element in cast irons, a relatively high silicon content is used to promote the formation of graphite.27. Cast irons have relatively low impact resistance and ductility, and this limits their use for some applications. 28. The wide industrial use of cast irons is due mainly to their comparatively low cost and versatile engineering properties. 29. Annealing is used with grey cast iron to provide optimum machinability and remove stresses. 30. To produce a fully ferritic matrix in a gray iron, the iron is usually annealed to allow the carbon remaining in the matrix to deposit on the graphite flakes, leaving the matrix completely ferritic.31. In the blackheart process, white iron casting in a non-oxidising atmosphere to 900 and soaked at that temperature for two days or more. 32. In permanent-mold casting the molten metal is poured into a permanent metal mold under gravity, low pressure, or centrifugal (sentrifjugl離心力)pressure only. 4. 分析題(1) 根據(jù)Fe-Fe3C相圖,圖中可以分為若干單項(xiàng)區(qū)和雙向區(qū),根據(jù)下面要求分別寫(xiě)出相組成。(注:liquid為液相、austenite為奧氏體相、ferrite 為鐵素體相、cementite為滲碳體區(qū)
