Strengthening mechanisms in ultra high strength corrosion resistant steel
EMSL Project ID
2306
Abstract
We are investigating the precipitation reactions that occur during high speed induction heat treatment of a ultra high strength corrosion resistant steel containing C,N,Cr, Ti V, Mo. We would like to use the Field emission SEM to analyze precipates that range size from 0.1 micron to 2. microns, smaller if possible. Interests include the chemistry of these precipitates and size distributions as a function of several heat treatment conditions. THe materials will be in the polished and etched condition and typically mounted in a conductive material. The precipitates are in a matensitic matrix. In some conditions an ultra fine precipitation of alloy carbides should be present on a size range of 10 nanometers. However we anticipate that TEM analysis will be required. We would like to discuss this as a future or next step analysis tool.
