Due to a combination of advantages, high-performance steel components, especially for automotive manufacturing applications, are generally forged parts. In the forging industry, bainitic steels being increasingly used, because they can reduce processing chain and energy consumption. this case, microstructure be obtained immediately after forging, with controlled cooling, without any subsequent ...

Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...

A numerical framework based on the generalized finite element method (GFEM) is developed to capture the coupled effects of thermomechanical deformations and thermal gradients on the regression rate of a heterogeneous solid propellant. The thermomechanical formulation is based on a multiplicative split of the deformation gradient and regression of the heterogeneous solid propellant is simulated ...

The conventional tubing supplied to oilfields with low aggressive environments: pCO 2 up 0.3 atm and pH S 0.005 often shows signs of pitting carbon dioxide corrosion after operation. To solve the problem, a new sparingly alloyed steel 25KhGB was developed for K grade increased set performance characteristics obtained thermomechanical treatment.

Abstract Advanced high-strength steels are key structural materials for the development of next-generation energy-efficient and environmentally friendly vehicles. Medium Mn steel, as one latest generation advanced steels, has attracted tremendous attentions over past decade due to its excellent mechanical properties. Here, state-of-the-art developments medium steel systematically reviewed with ...
