Hot deformation behaviour of 40CrNi steel and evaluation . 40CrNi steel is a low alloy steel with medium hardenability. After quenching and tempering, it has high strength and good low temperature impact toughness and thus is widely used in the manufacturing of A Characterization for the Deformation Behavior of As Thus, the application of the as-cast P91 alloy steel constitutive model on the CHE hot extrusion process should be further studied and explored. The finite element (FE) method is the efficient and economical alternative method for studying the flow stress behavior during hot deformation [1921]. Hence, the constitutive model of the as-cast Artificial neural network modeling to evaluate and predict The deformation behavior of type 304L stainless steel during hot torsion is investigated using artificial neural network (ANN). Torsion tests in the temperature range of 600-1200^oC and in the (maximum surface) strain rate range of 0.1-100s^-^1 were carried out. These experiments provided the required data for training the neural network and for subsequent testing.

Behavior of Hot-Mix Asphalt Containing Blast Furnace Slag

Significant amounts of blast furnace slag (BFS) are generated daily as by-product from iron and steel industries. This waste material usually has interesting physical properties and mineralogical and chemical composition, which can be useful as granular aggregate in the production of hot mix asphalt (HMA). Comparative Assessment on the Hot Deformation Behaviour Hot forged 1Cr1Mo and 9Cr1Mo steels are being progressively used in the making of the turbine rotors of steam power plants. Forging of these steels requires precise control of processing parameters (i.e. strain, strain rate and temperature) for a defect free product. In line with the above mentioned applications, a comparative study to analyze the hot deformation behavior of both the Constitutive analysis for hot deformation behaviour of Constitutive analysis for hot deformation behaviour of novel bimetal consisting of pearlitic steel and low carbon steel . Abstract . To understand the high temperature flow behaviour of a novel pearlitic steel (PS) and low carbon steel (LCS) bimetal, hot compression tests in a wide range of temperature and strain rate were conducted on a
