High-strain-rate nanoindentation behavior of fine-grained magnesium alloys
(Cambridge University Press (Materials Research Society), 2012-03)The effects of temperature and alloying elements on deformation in the high-strain-rate regime were investigated by testing fine-grained magnesium alloys with an average grain size of 2 ∼ 3 μm by a nanoindentation technique. ... -
High-strength transformation-induced plasticity steels with reverted interlath austenite
(Massachusetts Institute of Technology, 2022-02)The interlath austenite formed by reversion process increases the ductility of the martensitic steels. However, the reversion process requires high annealing temperatures and long annealing times, which lead to high energy ... -
