Research Outline

Hydrogen embrittlement and mitigation of hydrogen embrittlement by impurities

Effect of hydrogen on fatigue crack growth, fatigue life, fatigue limit, fracture toughness and other material strength properties are studied. Moreover, mitigation of hydrogen effect by impurity gases is studied.

Creep in hydrogen

Creep test in hydrogen at 600℃ is conducted. Effect of hydrogen on creep strength properties is studied.

Fretting fatigue in hydrogen

Metal fatigue involving friction and wear is studied.
