Resumo
The process of casting carbonless VZhM4 nickel superalloy cooled blades with a single-crystal 〈001〉 structure on UVNK plants is developed. Model blade units with seed parts for the formation of a single-crystal structure in a turbine blade are designed, the structure of the alloy is studied, and experimental batches of single-crystal blade ingots are cast. The influence of the directional solidification conditions on the structure of the carbonless alloy and the susceptibility of the single-crystal structure of the ingots to defect formation are investigated.
