Research overview:
Program comprises acquirement of characteristic intensity data of materials for domestic rockets, evaluation of their reliability, publication of data sheets, and improvement of reliability of the materials. To begin with, data sheets include test program settled for the first 5 years with materials used for FTP's and engines of H2A rocket and reused rockets of next generation. The experimental program for the data sheets comprises acquirement of such characteristic intensity data as tensile strength, Charpy impact data, fatigue data, and anti-fracture toughness data. In particular, we develop testing technique of fatigue at extremely low temperatures to effectively evaluate characteristics of long-term fatigue at extremely low temperatures, as well as testing technique of crack progress also at extremely low temperatures.
