WebIn general, the term ultrafine grain is used for average grain sizes between 1 μm and 2 μm in diameter. The term submicron structure refers to grain sizes between 100 nm and 1000 nm; and the term nano-structure means grain sizes below 100 nm. The formation of ultra-fine grained steels is an area of intense research around the world.
WebNormal stainless steel consists of large crystal grains with different sizes. Meanwhile, crystal grains are reduced in the fine-grained steel, which are manufactured by repeating plastic deformation and reverse phase transformation. The average grain sizes are 9.1 μm in the normal-grain steel and 1.52 μm in the fine-grain steel, respectively.
