Variant Pairing of Lath Bainite and Martensite in an Ultra-High-Strength Steel
Metals, 2022 The mixed structure of lath bainite and martensite was obtained by isothermal transformation tests at 698 K, 673 K and 623 K in ultra-high-strength steel. The interweaving mode of lath bainite and martensite was revealed by colored metallography and band

The impact of hydrogen on the ductility loss of bainitic Fe–C alloys [PDF]
, 2016 The influence of hydrogen on the mechanical properties of generic lab-cast Fe-C bainitic alloys is studied by tensile tests on notched samples. The bainitic microstructure is induced in a 0.2% C and 0.4% C Fe-C alloy by an appropriate heat treatment. The
