| Abstract: | It is important to study the effects of modifying on molybdenum products structure.Research achievements from abroad and the composition of grain boundary for molybdenum compacts at home are introducted and studied.Results showed that there are two kinds of molybdenum compacts,A and B.In A there are elements of potassium and silcone over 0.087 percent ,and rare earth elements over 0.02 percent.In B the content of rare earth elements is less than 0.02 percent.Kind and content of modifying elements in molybdenum compacts depend on molybdenum resources and processing control of powder metallurgy. |
