The Effect of Hot Deformation Parameters on Grain Size Refinement in a Martensitic Stainless Steel
The grain size refinement of AISI 422 martensitic stainless steel in the temperature range of 950-1150 ºC was investigated by hot deformation tests. The deformed specimens were held at deformation temperature with delay times of 5 to 300s after achieving a strain of 0.3. The austenite grains exhibit a considerable growth at temperature higher than 1050˚C, while the grain coarsening is negligibl...
متن کاملElectrochemical Characterization of a Martensitic Stainless Steel
This paper focused on the characterization of electrochemical behavior of a martensitic stainless steel in the acidic solutions. For this purpose, electrochemical parameters were derived from potentiodynamic polarization, Mott Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that corrosion current density of AISI 420 ...

متن کاملThermoelectric Power Studies on a Martensitic Stainless Steel
In this work the different contributions to the thermoelectric power (TEP) measurement during the dissolution process of M23C6 carbides in an X45Cr13 stainless steel have been evaluated. Thus, the influences of carbon and chromium contents in solid solution in the austenite, the austenite grain boundaries and the microstructure on the TEP have been determined.
متن کاملSegregation of Boron to Grain Boundaries in Iron and a Stainless Steel
The effects of boron on the grain boundary and surface energies in iron at 900 and 1000 OC and AISI 316 stainless steel in the temperature range 950-1 250 OC were investigated. It was found that boron reduced these energies in a manner typical of an element with low solubility in the matrix. It has been found that boron improves the grain boundary strength of iron at low temperatures [I] and in...
