In the present study, isothermal decomposition of austenite to bainite in 1.0 wt% carbon, 0.21% silicon steel during partitioning step a quenching and (Q&P) heat treatment has been investigated dilatometer temperature range 200 350 °C compared conventional austempering treatment. The transformation was shortened by about 75% presence pre-existing martensite (QP). kinetics is described well-...

multiwall carbon nanotubes (mwcnts) are grown via chemical vapour deposition method directly on a stainless steel substrate. raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. after their removal from the stainless steel substrate, the as-grown mwcnts are then a...

in hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. in this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. specimens of low carbon silicon-free steel with d...
