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.

Stainless steel (SS) is used for many commercial and industrial applications owing to its high resistance to corrosion. It is too hard to machine due to its high strength and high work hardening property. A surface property such as surface roughness (SR) is critical to the function-ability of machined components. SS is generally regarded as more difficult to machine material and poor SR is obta...

Austenitic Type 304L stainless steel (SS) and martensitic Alloy EP-823 have been identified as candidate structural materials to contain spallation arget for transmutation of nuclear waste. Welded specimens consisting of either or both materials have been evaluated by transmission electron icroscopy (TEM) to determine the dislocation density near the heat-affected-zone (HAZ) and the base materi...

17-4PH stainless steel is a martensitic precipitation hardening stainless steel that provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties, good toughness in both base metal and welds, and short time, low-temperature heat treatments that minimize warpage and scaling. This valuable alloy is widely used in the aerospace, nuclear, chemical, pet...

in the present study, the microstructure and mechanical properties of the dissimilar welding betweenastm a335 low alloy steel and er309l austenitic stainless steel were investigated using the gastungsten arc welding process. the welding of dissimilar materials between astm a335 low alloy steeland er309l austenitic stainless steel was found to have a significant effect on the microstructure when...

We report a design strategy to combine the benefits from both gradient structure and transformationinduced plasticity (TRIP). The resultant TRIP-gradient steel takes advantage of both mechanisms, allowing strain hardening to last to a larger plastic strain. 304 stainless steel sheets were treated by surface mechanical attrition to synthesize gradient structure with a central coarse-grained laye...
