Abstract AITranslate

By testing the micro-yield strength,thermal expansion coefficient,and dimensional changes of the isostatically pressed beryllium material,its dimensional stability against load and temperature changes was studied.The results show that the micro-yield strength of isostatically pressed beryllium material is relatively high,with an average value of 127.4 MPa,which is 53.5%higher than the equivalent beryllium materials published in the United States.Isostatically pressed beryllium material has a relatively low thermal expansion coefficient,and its longitudinal and horizontal average linear expansion coefficients in the temperature range of 25~100℃are 12.02×10-6/℃and 11.89×10-6/℃,respectively.The total axial resi-dual strain of isostatically pressed beryllium material is small after repeated cooling and heating cycles,about-18×10-6after 15 cycles,and its dimensional thermal stability is excellent.
