3. 2. Low-temperature carburizing/nitriding of austenitic stainless steels - Influence of alloy composition on microstructure and properties

   Författare :Giulio Maistro; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; surface engineering; S-phase; SEM; corrosion; XPS; Austenitic stainless steel; expanded austenite; plasma nitriding; EBSD; XRD; thermal stability; low-temperature carburizing; surface analysis; GDOES;

   Sammanfattning : Austenitic stainless steels are among the most used materials in applications where corrosion resistance is important, as the food, pharmaceutical, chemical, oil and gas industries. However, low hardness and poor tribological properties is often an obstacle for their applicability. LÄS MER

4. 3. Hydrogen embrittlement and corrosion behavior of low-temperature carburized austenitic stainless steel

   Författare :Xiao Qin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature carburising; hydrogen embrittlement; Austenitic stainless steel; microstructure; corrosion behavior; expanded austenite;

   Sammanfattning : For metallic components used in hydrogen environments, hydrogen embrittlement and corrosion have always been important considering potential failure risks. Among many metallic materials, austenitic stainless steel has found broad application because of its excellent corrosion and hydrogen embrittlement resistance. LÄS MER

5. 4. Microstructural Characterization of Expanded Austenite in 304L and 904L Austenitic Stainless Steels

   Författare :Giulio Maistro; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature thermochemical treatment; S-phase; SEM; thermal stability; surface engineering; surface analysis; EBSD; XRD; austenitic stainless steel; XPS; GDOES; Expanded austenite;

   Sammanfattning : Austenitic stainless steels are among the most used materials in modern industry, mainly because of their superior corrosion resistance. However, low hardness and poor tribological properties often restrict their applicability. LÄS MER

7. 5. Hardening Distortions of Serial Produced Gears

   Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER
