“…Furthermore, Figs. 8 and 14 show that as the eigenvalues are increased, the temperature within the medium also increases [23], and this corresponds to temperature increase within a medium as heat accumulation therein increases.…”

In this article the distribution of temperature in both smooth and stepped functions is compared. The study uses a model of one dimensional N-cross-sections domain of a vase shaped medium, where approximation of the solution in the first case uses smooth functions, and in the second one, stepped functions. The temperature distribution is described by heat equation. Analysis of temperature distribution in both cases is based on finding eigenvalues and their corresponding eigen-functions which satisfy boundary conditions at given endpoints. Mathcad software was applied to determine the eigenvalues and their corresponding eigen-functions, together with the temperature distribution in the media of concern. The temperature distribution in both cases was found to be basically the same. The problem solution for each case is presented and an example of a one-dimensional vase shaped domain of length 4 units for each case is also given.

“…The temperature control curve and the test temperature for the hot tensile test are shown in Figure 1b. Combined with the research on Gleeble test parameters, [ 25 ] while collecting and analyzing the secondary cooling water amount of the plant, the specific water volume of this steel under weak cooling conditions is about 0.32 L kg −1 , which is converted into a cooling rate of about 95 °C min −1 , Under the condition of strong cooling, the specific water volume of this steel is about 0.58 L kg −1 , which is about 173 °C min −1 . Based on the aforementioned results, for the convenience of comparative analysis, the strong cooling and weak cooling are set to 3 and 1.5 °C s −1 , respectively.…”

To figure out the formation mechanism of transverse corner cracks at the inner and outer arc of peritectic steel slab, the metallurgical microscope, scanning electron microscope with energy‐dispersive X‐ray spectroscopy, and electron probe‐X‐ray microanalysis, are used to study cracks. High‐temperature mechanical properties and the stress distribution of the outer arc of the bending section under different roll gap schemes are studied and simulated. The outer arc cracks expand along the grain boundary, while the inner arc cracks not only extend along the grain boundary but also traverse along the grains. The outer arc cracks are mainly generated at the bending section and are formed and expanded along the ferrite film. The inner arc cracks' cracking temperature is higher than the temperature of austenite transformation to ferrite. The third brittle temperature ranges are 650–850 °C, and the transverse corner crack sensitivity zone is 680–837 °C. The inner arc cracks are generated because of the element segregation and low temperature of the corner and then extended at the straightening section, and new cracks exist. The weakened cooling intensity and bending earlier at the bending section help to reduce the equivalent stress on the slab. The optimized experiments are conducted, and the transverse corner cracks are reduced significantly.
