Because the process supplyment affect the quality of piece forming greatly, here the influence of process supplyment fillets on piece forming is also analyzed, the suitable process plan are finally gained.
In this paper, an optimum design of transient fillets in the housing has been carried out by a program package-OPTSDP for optimal design of the shape using FEM, with rapid redesigning function.
Based on different theories and techniques for the reduction of stress concentration, and on the basis of forms of breech ring fillets in general use, over a dozen of fillet forms are proposed.
These results suggested that increased dietary α-tocopheryl acetate could increase its flesh deposition, increase the activity of SOD and prevent lipid peroxidation of Sparus macrocephalus fillets in retail storage on ice.
The peak stresses appeared at the slot corners inside the adhesive fillets and at the horizontal and vertical plate outer fibres corresponding to the two slot free ends.
The steady state heat transfer analysis showed that the temperature distribution through the joint members was non-uniform and high heat fluxes occurred inside the adhesive fillets at the adhesive free ends.
The influence of 28 element additions on the melting point, flowability, corrosion resistance and fillet bending ability of A1-Si type filler metal has been investigated. Among these systems, filler 6M, i. e.A1-Si(13.0)-Be(0.4—0.8)-Sr (0.03—0.06)-La (0.03—0.06) is regarded as the optimum. The erosion mechanism of molten filler metal on base metal has been also studied. In addition to the influences of brazing temperature and the composition of filler metal, the rate of solution of base metal into molten fil...
A study has been made of the effects of twenty metal additions in small amount on the corrosion resistance in 3% NaCl solution of Al-Zn euteetic fillets on pure aluminum as well as on LY12 (2024) base metals as determined by weight loss and by metallographic technique. It is shown that corrosion resistance effectively increses with the addition of small amounts of alkaline earth and rare earth elements, such as Be, Mg, Sr and La. The addition of heavy metals, such as Bi, Sn, Pb, Cd, Tl, Cu, Ni and Ga ...
It was shown from experimental results that excellent brazability of aluminiumalloy could be obtained with magnesium activator in vacuum brazing.It was thepurpose of the present study with the help of Auger electron spectroscopy and Scanningelectron microscopy surface analysis to research for variation of magnesium constituentand surface configuration of brazing filler metal layer on composite sheet specimens.At different temperature the concentrated evaporation of magnesium constituent atmelting temperatur...
