6.2.3 The Bainite structure. The bainitic microstructure was first identified as a result of systematic isothermal transformation experiments by Davenport and Bain,18 who reported the

Depending on the temperature, two different structures can be the and the bainite (Figure 1). Figure Structure of bainite needles, lower bainite, B) upper bainite structure . The hardness of bainite varies from about 40 HRC for upper bainite to about Rockwell 60 HRC for lower

The H steel is mainly used as a beam or pillar component for industrial and civilian construction projects. Specific applications are listed here. 1. Steel support bracket for industrial structures. 2. Steel pile and supporting structure for underground construction. 3. Structure of equipment in petrochemical and power

Jun 01, Bainite and martensite were distinguished by combining dilatometry, SEM and EBSD. using a 15 kV electron beam and the Secondary Electron Imaging (SEI) detection mode. 3. Results and discussion3.1. Effect of martensite in initial structure on bainite transformation. Mater Sci Forum, 638-642 (2010), pp.

Oct 21, Bainite as a phase mixture has been known since the 1930s, but the scale of the structure in ordinary steels is in the micrometre range. It is, however, known that the structure can be refined by reducing the transformation temperature (Singh Bhadeshia 1998). It is of interest therefore to investigate the lowest temperature at which bainite

Bainite, as a two-phase microstructure, consists of ferrite and iron carbide. There is a variation in the morphology of bainite and in the type of carbide (Fe 3 C, or carbide or Fe 2. 4 C) depending on the temperature of transformation and the composition of the steel as illustrated in Fig. 3.36. Bainitic microstructure can be divided into

May 20, The high cooling rate of low heat-input welds further reduces the time for diffusion to occur, resulting in the formation of lower bainite + lath martensite in the CGHAZ (Figure 8). When HSLA steels are welded using high heat inputs, the resultant slow cooling rate elongates the time for the transformation from austenite to upper bainite, which
