; accepted 25 June 2010 Abstract:Although thixoforming of low melting point alloys as aluminum or magnesium is now an industrial reality, thixoforming of high melting point alloys as steel is still... in classical hot forging. Beyond this, the failure modes of hot-work tool steel, the X38CrMoV5 or H11, were presented. Key words: thixoforging; steel; high melting point; tool; material 1 Introduction......

, the relationship between the melting properties of fluoride-free mold fluxes and fusing reagents, binary basicity and TiO2 content was investigated by measuring the viscosity and melting point of the melted slag. The experimental result indicates that the effective compositions in lowering the viscosity and melting point are B2O3, Na2O and Li2O, in which the effect of B2O3 is the most remarkable; When......
. This characteristic requests that the melting method must be convenient to control the component evaporation of TiAl melt. From this point, electron beam melting furnace, popular to melt titanium... mass to melting point to the total energy consumption (Q/Emin). Q can be calculated by Eqns.(12) and (13). cp=55.940+5.94×10-3T-7.531×105T-2(13) And then Q=1210.8kJ/kg. Since The varying curve......
is of great interest because of its corrosion-resistance, and high melting point. However, it is difficult to make the intermetallic compound using the ordinary method. [全文内容正在添加中] ......
and the temperature in the vicinity of the melted zone will remain high. This high temperature assists full melting of the powder in the next layer. Therefore, the density of the specimen depends on the supplied... has a significantly higher melting point than SS 316L powder. Thus the thermal stresses that develop because of the differences in thermal expansion coefficient may lead to hot tearing [11]. Fig. 5......
