中文摘要 | 本研究主要探討Fe-C-Si-Mo系合金延性鑄鐵之高溫拉伸性質與耐氧化性質;試料之碳含量固定為3.8wt%,針對不同矽添加量(3.8wt%、4.0wt%、4.2wt%)及不同鉬添加量(0.6wt%、0.7wt%、0.8wt%),探討在不同溫度(973K、1073K、1173K)時之高溫拉伸性質及在1073K(800℃)時之耐氧化性質,並利用金相顯微鏡觀察組織之變化。 實驗結果得知,高溫拉伸性質方面:添加4.0%Si-0.8wt%Mo的試片分別在973K、1073K、1173K時,其高溫抗拉強度最佳,分別是230.7MPa、88.6MPa、37.6MPa;耐氧化性方面:在1073K(800℃)時,添加4.0%Si-0.8wt%Mo的試片其耐氧化性最佳,重量變化率小於0.1%。由此可知添加合金鉬能有效提高Fe-C-Si-Mo系合金延性鑄鐵之高溫拉伸性質與耐氧化性,將有利於在工業上高溫環境下之實際應用。 |
英文摘要 | The objective of this study is to investigate the high temperature tensile property and oxidation resistance property of Fe-C-Si-Mo ductile cast iron. The carbon content of specimen is fixed at 3.8wt%, but the Si contents (3.8%, 4.0%, 4.2wt%) and the Mo contents (0.6%, 0.7%, 0.8wt%) are varied. The high temperature tensile property at different temperatures (973K, 1073K, 1173K) and the oxidation resistance at 1073K (800℃) are studied, moreover, the microstructure changes are observed by using a optical microscope. It is observed from this research that the specimen with 4.0wt% Si and 0.8wt% Mo possesses the best high temperature tensile strengths at 973K, 1073K, 1173K; the tensile strengths are 230 MPa, 88.6 MPa, and 37.63MPa, respectively. The specimen with 4.0wt% Si and 0.8wt% Mo processes the best oxidation resistance property at 1073K (800℃); and its weight increment rate is less than 0.1%. The experimental results show that the high temperature tensile property and oxidation resistance property of Fe-C-Si-Mo ductile cast iron can be enhanced effectively by adding alloying element Mo; it would be beneficial for the practical high temperature application in the industry. |
