Lath Martensite - an overview ScienceDirect

Figures 2.6(a) and (b) (Morito et al., 2003a) show a SEM image of a block structure within a packet of lath martensite in an ultra-low-carbon alloy, and the corresponding orientation image map obtained through EBSD analysis.Each block, with a little different contrast in SEM (Fig. 2.6(a)), corresponds to substantially different contrasts in the orientation image map (Fig.

Plate Martensite - an overview ScienceDirect

In Pergamon Materials Series, 2007. 4.4.1.2 Twin boundaries and plate boundaries. A large proportion of the partitioning interfaces in the internally twinned plate martensite structure is constituted of 0 I twin interfaces. Some of these are boundaries separating adjacent twins within single plates while some others are located between contiguous martensite plates obeying

Martensitic Structure - an overview ScienceDirect

The martensitic structure formed after austenitisation and tempering is not on exposure at envisaged service temperatures around 600 recovery processes occur, the dislocation density within the martensite laths decreases, and a ferrite subgrain structure is formed. It has been found that only after 3000 h exposure at 600 a more or less stable microstructure is achieved, as

bainite wear resistant steel plate

The structure and mechanical properties and weld properties of bainite wear resistant plate without carbide were studied The results the structure of bainite without carbide is obtained if proper quantum of silicon is added into low carbon bainitic

Martensite Transformation - an overview ScienceDirect

The martensite transformation is diffusionless, and therefore martensite forms without any interchange in the position of neighbouring atoms. Accordingly, the observed orientation relationships are a direct consequence of the atom movements that occur during the transformation. The first suggestion of a possible transformation mechanism was made by Bain

1. Introduction. Martensite in steels over the millennia has been used to do work, to do battle, and to support mechanical loads. Applications range from ancient elegantly crafted hand tools and swords , to current high-strength, high-fatigue resistant, high-wear resistant parts for machines, tools and dies, power transmission, gears and shafts, and demanding load-bearing structures such as

Metallurgy Phases, structures, and the influences

When you heat or cool a piece of metal to a specific temperature, that metal goes through what\'s called a phase change, in which its crystal structure changes. Sometimes the change is obvious. For example, when a piece of metal melts, it goes through a phase change when the crystal structure breaks down and the metal goes from solid to liquid. When it solidifies it\'s also a phase change,

Hydrogen Embrittlement in Plating -

Hydrogen--often from pickling or plating--invades the grain structure of a high strength steel, making it brittle and subject to catastrophic failure. The best approach is to avoid or minimize processes that cause hydrogen embrittlement. The second best approach is to bake the parts to drive the hydrogen out, preferably very soon after
