Abstract: In this paper, a new solution of solidification problems in continuous casting based on meshless method is presented with multiple strategies to solve the practical problems. An additional term is added to stabilise the computation with Neumann boundary. The enthalpy method is used to calculate the latent heat and the corresponding iterative solution is given. An iteration scheme for ...

In the original evacuation scheme, drawn up to meet a contingency that was still theoretical and hopefully remote, attention was largely concentrated on the Process of getting children out of London and other vulnerable areas and on the task ?f ensuring that a billet of some kind was available for every child who needed it. On the whole, the schemes worked amazingly well and there was no lack o...

V. A. Andreyachshenko Faculty of Nanotechnology and Metallurgy, Karaganda state technical University, Karaganda In the paper there is studied stressed-and-strained state formed in a billet by fullering in a tool with movable elements. It is determined that compressing stresses prevail in the studied tool; they improve the quality of the processed billets. Even maximum main normal stresses have ...

Abstract. This study is focused on understanding the effects of key process parameters onset recrystallisation coarse, elongated, and dendritic grains as-cast microstructure during ingot-to-billet conversion, consisting successive cogging, upsetting, reheating operations, in type 316 austenitic stainless steel. The microstructural characteristics initial ingot (e.g., size, orientation morpholog...

Recently evolving Solid-State Recycling (SSR) techniques have shown promising features to recycle metals scraps more efficiently compared remelting-based approaches. Among these SSR methods, Friction Stir Consolidation (FSC) has been successfully tested transform chips directly into semi or final solid products. Therefore, researchers explored FSC critical process parameters and their subsequen...

This paper performs a comparative analysis between as-cast and semi-solid CuSn10P1 in state of hot compression deformation. Compared to original billets, the brittle phases intergranular microstructures are reduced, while tangled dislocations occur inside β’-Cu13.7Sn phase, generating slipping bands twins. The precipitation reduction phase smaller difference Young's modulus matrix contribute im...

The liner of a compressed natural gas pressure vessel is manufactured by D.D.I. (deep drawing and ironing), which continuous process that uses deep to reduce the diameter billet ironing thickness billet. In second stage existing process, two steps have been performed separately with different dies, requires long processing time, high manufacturing cost, installation space. To solve above proble...
