2. 1. High performing cast aluminium-silicon alloys

   Author : Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

   Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

4. 2. On particles and slags in steel casting

   Author : Dimitrios Siafakas; Anders E.W. Jarfors; Taishi Matsushita; Sridhar Seetharaman; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; viscosity; slag;

   Abstract : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. READ MORE

5. 3. The effect of workpiece material and its microstructure on tool wear in metal cutting

   Author : Philipp Hoier; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scanning electron microscopy; Superalloy; Cutting tool; Wear; Cemented carbide; Steel; Machining;

   Abstract : The aim of the present work is to promote the basic understanding of how the workpiece material and its microstructure affect the tool wear during metal cutting. To isolate the effect of the workpiece material, the tool material (uncoated cemented carbide) was kept constant while the workpiece was varied. READ MORE

6. 4. Decarbonising the Stainless Steelmaking through Alloy Solutions

   Author : Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

   Abstract : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. READ MORE

7. 5. Development of Structural Steels for Powder Bed Fusion - Laser Beam

   Author : William Hearn; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; in situ tempering; process development; martensite; additive manufacturing; cold cracking; low-alloy steel; structural steel; powder bed fusion – laser beam; carbon steel;

   Abstract : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. READ MORE
