Secondary Solidification

Rheo-die casting (RDC) based on LSPSF (low superheat pouring with a shear field) rheocasting process has been exploited. In case of secondary die casting aluminum alloy YL112, LSPSF allowed for preparation of sound semi-solid slurry in 15-20s that fully meet the production rate of HPDC, the primary α-Al exhibiting a mean equivalent diameter of 70 μm and shape factor of 0.93, without any entrapped eutectic. Compared to conventional HPDC, RDC improves microstructures in castings. Secondary solidification of semi-solid slurry takes place uniformly throughout the entire cavity, producing an extremely fine and uniform microstructure. The experimental results show the RDC 380 alloy has much improved integrity and mechanical properties, particularly elongation, and heat treatment can be used to enhance the mechanical properties.

We compared the newly developed heat resistant magnesium alloy with conventional ones by Thixomolding® and aluminum alloy by die casting. Tensile properties at elevated temperatures of AXEJ6310 were equal to those of ADC12. In particular, elongation tendency of AXEJ6310 at higher temperature was better than those of the other alloys. Creep resistance of AXEJ6310 was larger than that of AE42 by almost 3 orders and smaller than that of ADC12 by almost 2 orders of magnitude. Fatigue limits at room temperature and 423K of AXEJ6310 was superior among conventional magnesium alloys.

Stress And Deformation

In the welding process, the welding strain and deformation of the city rail aluminum alloy flankwall are inevitable as a result of local heating, and carrying capacity of the structure will be affected by the welding stress and deformation. In the mean time, it puts forward some requirements for the clamp process, the clamping force can reduce the deformation of the workpiece. But a great change of force will produce in the clamp position during the process of welding, this force changes are easy to cause brittle fracture and fatigue damage of the clamp. In this paper, it gives simulation analysis to workpiece by using ANSYS analysis software and Gauss heat source model. Finally, the conclusion is sum up compared with the actual data.

Design Requirements

Technology requirements for a billet micro globular structure development and following deformation are the basic inputs in a conceptual forging equipment design. The R&D team has studied the features of the Aluminum alloy thixoprocess experimentally on a crank press as well as with a help of computer simulation and have formulated requirements for SSM technology CNC prototype unit development.
