Surface and Bulk Carbide Transformations in High-Speed Steel
We have studied the transformation of carbides in AISI M42 high-speed steels in the temperature window used for forging. The annealing was found to result in the partial transformation of the large, metastable M2C carbides into small, more stable grains of M6C, with an associated change in the crystal orientation. In addition, MC carbides form during the transformation of M2C to M6C. From the h...
متن کاملProperties of Low-alloy High-speed Steel at Elevated Temperature
J. Jaworski, T. Trzepieciński: Faculty of Mechanical Engineering and Aeronautics, Rzeszow University of Technology, Rzeszów, Poland This paper presents the results of research on the determination of the coefficient of thermal conductivity and hot hardness of cutters made of selected grades of low-alloy high-speed steels, HS 6-5-2 and HS3-1-2. The investigations of hot hardness and yield stress...
متن کاملThermal and Phase Transformations Analysis in a Premomet® Steel
M. Torres-Lopez, L. Guerra-Fuentes, L. Y. Gomez-Zamorano, M. A. L. Hernandez-Rodriguez, E. Garcia-Sanchez. University Autonomous of Nuevo Leon. Thermal analysis in a PREMOMET® steel has been performed by differential scanning calorimetry (DSC) and highresolution dilatometry. The phase transformation temperatures (Ac1, Ac3, Ms and Mf) of this steel were obtained by the two methods at different h...
متن کاملA Numerical Study on Agglomeration in High Temperature Fluidized beds
Soft-sphere discrete element method (DEM) and Navier-Stokes equations were coupled with equations of energy for gas and solids to investigate the process of agglomeration in fluidized bed of polyethylene particles at high temperature. The Newton’s second law of motion was adapted for translational and rotational motion of particles and agglomerates. The cohesive force for polyethylene particles...
متن کاملShock temperature of stainless steel and a high pressure — high temperature constraint on thermal diffusivity of Al 2 O 3
Time dependent shock temperatures were measured for stainless steel (SS) films in contact with transparent anvils. The anvil/window material was the same as the driver material so that there would be symmetric heat flow from the sample. Inferred Hugoniot temperatures, Th, of 5800-7500K at 232-321GPa are consistent with previous measurements in SS. Temperatures at the fihn-anvil interface (T,), ...
