Martensite in Steels
The name martensite is after the German scientist Martens. It was used originally to describe the hard microconstituent found in quenched steels. Martensite remains of the greatest technological importance in steels where it can confer an outstanding combination of strength (> 3500MPa) and toughness (> 200MPam 1 2 ). Many materials other than steel are now known to exhibit the same type of soli...
متن کاملEffect or Inoculation on Microstructure and Properties of Low C-Mn and Low Alloy Steels
Effect of the addition of various inoculants on the morphology and mechanical properties of low C-Mn and low alloy steel samples is studied by thermal and mechanical processing of the samples after solidification. According to the results obtained from metallographic studies with the electron microscope and microanalysis with x-rays, the distribution of inoculating agents in the steel matrix is...
متن کاملThe Silicon Effect in the Tempering of Martensite in Steels
High-silicon steels have long been known to possess exceptional resistance to tempering, but the reasons for this effect were unknown. We report here a study of the third stage of tempering of these steels, in which cementite is formed. In a 0.75 wt% C 1.4 wt% Si alloy steel, tempered for 1 hour at 380°C, it is found that silicon atoms are rejected from the growing cementite into the ferrite ma...
متن کاملCorrosion Behaviour of High-Mn TWIP Steels with Electroless Ni-P Coating
An attempt has been taken to improve the corrosion resistance of twinning-induced plasticity (TWIP) steels (Fe-25Mn and Fe-25Mn-3Al) by electroless Ni-P coating. Corrosion resistance in 3.5% NaCl and 0.1M H2SO4 solutions was characterized by the potentiodynamic polarization curves and Tafel method calculations. It was found that Ni-P coating improved the corrosion resistance by the factor of 4 ...
