Intragranul strains and mosaicity in alpha and gamma phases of a duplex steel...

Hydrogen absorption in steel induces embrittlement, reducing tensile strength, fatigue resistance, and fracture toughness. In duplex steel, hydrogen expands the austenitic fcc...钢中的吸氢现象会诱发氢脆效应，进而导致材料的抗拉强度、抗疲劳性能与断裂韧性下降。在双相钢（duplex steel）中，氢会使奥氏体面心立方（face-centered cubic，fcc）相发生膨胀……
