    1. 32. AN OVERVIEW OF MECHANICAL PROPERTIES OF TODAY'S GRAIN-REFINED AUSTENITIC STAINLESS STEELS

      Oral Presentation
      In recent years numerous studies have demonstrated that a short reversion annealing following cold rolling is an efficient method to refine the grain size of metastable austenitic stainless steels down to a micron-scale. Commercial grades such as EN 1.4310 (AISI 301) and EN 1.4318 (AISI 301LN), EN 1.4371 (AISI 201L) have been found suitable for the treatment. In addition to resistance heating...

    2. 33. INFLUENCE OF HEAT TREATMENT AND THERMOCHEMICAL SURFACE ENGINEERING ON THE HIERARCHICAL MICROSTRUCTURES OF 3D PRINTED AUSTENITIC STAINLESS STEEL

      Oral Presentation
      Additive manufacturing (AM) of austenitic stainless steel has been shown to be capable of producing samples with a unique combination of high strength and ductility. This increase in yield strength without the conventional ductility trade-off is usually attributed to the non-equilibrium, hierarchical microstructure produced by AM, particularly the cellular subgrain structures and dislocation...

    3. 39. MONITORING THE SURFACE QUALITY OF STAINLESS STEEL SLABS WITH REVEAL CAST - FINDINGS AND SUB-SEQUENT QUALITY IMPROVEMENTS

      Austenitic stainless steels
      Oral Presentation
      Quality of stainless steel semi-products is important for the cost-efficient production of final products. Yield losses due to the excessive grinding, losses due to the down-grading or scrapping the whole semi-finished product may impair the profitability of the production. By monitoring the surface quality of the hot slabs during the casting on line, it is possible to get valuable information...

    4. 45. THE EFFECT OF HEAT TREATMENT AND SURFACE HARDENING OF 3D PRINTED AUSTENITIC STAINLESS STEEL AlSl316 ON CORROSION AND WEAR PROPERTIES

      Austenitic stainless steels
      Oral Presentation
      Due to the high cooling rates and layer by layer building characteristics of the additive manufacturing (AM) process Selective Laser Melting (SLM), the as-fabricated parts can contain strongly inhomogeneous microstructures, porosities, rough surfaces and residual stresses. For example, the as-fabricated microstructure of SLM 316L typically consists of elongated austenite grains with a cellular...

    5. 47. HIGH NITROGEN HIGH CARBON STAINLESS STEEL

      Austenitic stainless steels
      Oral Presentation
      High strength medium carbon austenitic stainless steels have been developed through partial and total replacement of nickel by nitrogen. Stainless steels containing 0.4% carbon with different combinations of nickel and nitrogen were produced in 10kg induction furnace under different nitrogen pressures. The produced stainless steels were cast and hot forged and the total nitrogen was...
