cryogenic ultrafine тээрэм
Superior cryogenic tensile properties of ultrafine-grained CoCrNi ... The true stress-strain curve of the UFG sample at cryogenic temperature is presented in Fig. 2.The cryogenic temperature tensile curve of the FG sample (HPT + 700 °C for 60 min ~1.5 μm) and CG sample (HPT + 900 °C for 60 min ~20 μm) are also shown in Fig. 2 for comparison.
