Hydrogen effect on mechanical properties of IN738LC superalloy
Popis výsledku v původním jazyce
The study of hydrogen effect on mechanical properties was carried out on samples of IN738LC superalloy. Two ensembles of tensile specimens in the heat treated state were prepared: hydrogen-charged and without hydrogen treatment. The hydrogenation was performed at 800 oC for 4 hours in flowing hydrogen gas. Tensile tests were realized on both ensembles of samples with a strain rate of 5.8 x 10-5 s-1. The yield strength and tensile stress of the superalloy samples non-hydrogenated reached the average values of 717 - 9 MPa and 800 - 18 MPa, respectively. The hydrogen effect resulted in a rise of the average values of yield strength as well as of tensile stress to 800 - 55 MPa and 843 - 32 MPa, respectively. The hydrogen content in two selected specimens was measured using LECO RH600 analyzer and the values of 47.6 and 71.4 ppm of hydrogen were determined. Metallographic and fractographic studies as well as microanalysis of selected specimens were carried out after tensile testing. Casting
