Creep deformation of austenitic steels at medium and low temperatures
Cryogenics, 1999 Abstract An austenitic steel used as a structural material of a superconducting magnet undergoes creep deformation and stress relaxation even at medium and low temperatures. Small plastic and creep strains in eight austenitic steels and a low-alloy steel were measured in the temperature range from 4 to 573 K. Every steel including the low-alloy steel

Materials and Corrosion, EarlyView.The hardness and corrosion resistance of the martensitic stainless steel X30Cr13 depend directly on the applied heat treatment. This article describes and discusses the relationships between alloy composition, thermodynamic phase stabilities, heat treatment parameters, resulting microstructures, and achievable corrosion resistance. To investigate these

steel research international, EarlyView.The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels
steel research international, EarlyView.The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

High-temperature quality of accelerated spheroidization on SUP9 leaf spring to enhance machinability
Heliyon, 2018 The high temperature on the austenitization showed the varied results in the fast spheroidization in high carbon leaf spring steel SUP9/55CrMnA. The heating temperature was held for 15 minutes in the austenitization temperature at 800, 850, and 900 °C ...

steel research international, EarlyView.To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.
