Effect of crystallographic orientation on mechanical properties of high-temperature alloys
It is known that cast heat-resistant alloys with a directed structure have a higher high-temperature strength than alloys with an equiaxial structure. For this reason preforms of turbine blades are often produced using the method of directed crystallization, which provides a columnar and single-crys...

Summary: | It is known that cast heat-resistant alloys with a directed structure have a higher high-temperature strength than alloys with an equiaxial structure. For this reason preforms of turbine blades are often produced using the method of directed crystallization, which provides a columnar and single-crystal macrostructure. However, it is difficult to provide a strictly constant orientation of crystallites in batch production of blades. The author analyzes special features of the effect of the orientation of the crystallites on the properties of high-temperature alloys.[PUBLICATION ABSTRACT] |
