The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

Recording Characteristics of Acicular Cobalt-ferrite Tape.
Two kinds of acicular cobalt ferrite fine particles which differed in size (long axis : about 1.2μm and 0.4μm) were prepared by conventional sintering method. Then two kinds of acicular cobalt ferrite tapes were fabricated with these fine particles and binder regins.

This study investigated the effect of subcritical heat treatment and cold work on the hydrogen embrittlement (HE) susceptibility of the X65 D pipeline steel. Hydrogen charging reduced the ductility of all specimens. Both subcritical annealing and cold working decreased somewhat the degree of HE.
