Optimum Chemical Composition and Thermomechanical Processing Condition for Niobium-Boron Steel

Effect of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Duplex Stainless Steel

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...

Thermomechanical Damage Modeling of F114 Carbon Steel

Abstract—The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as fracture. But, the results of such numerical model depend strongly on the parameters of the constitutive behavior model. The influences of thermal and m...

Chemical diffusivity of boron in melts of haplogranitic composition

A~~~-~erni~ Asiatic of B in synthetic melts of hapl~~tic composition have been measured by the diffusion couple technique at 1 atm between 1200-1600°C. The compositional profiles were measured by ion microprobe and modelled using the Boltzmann-Matano formalism to retrieve compositionally dependent interdiffision coefficients. At the experimental conditions, &OS is found to exchange primarily wi...
