=Ag, Bi, In, Sb) solders were examined. The findings revealed that the introduction of Ag, Bi, In, and Sb minimally altered the solidus temperature, liquidus temperature, and tensile strength... behavior of the SCNG-x solders was determined in terms of the solidus temperature and liquidus temperature. Figure 2 shows DSC thermograms of the SCNG-x specimens during heating (H) and cooling (C......
to examine the partition of alloying elements between γ matrix and γ? precipitates. 2.3 Differential scanning calorimetry (DSC) analysis The influence of Cr addition on the liquidus and solidus temperature... elements in two alloys Figure 2 shows the heating curves of the two alloys in DSC experiment. It is clearly seen that more Cr addition significantly decreases the solidus and liquidus temperatures (TS......

钢种和断面对连铸板坯轻压下效率的影响林启勇1,朱苗勇2(1.重庆市中冶赛迪工程技术股份有限公司自动化事业部2.东北大学 材料与冶金学院,辽宁沈阳 110004)摘 要:结合轻压下效率的理论计算式,考察了板坯断面,钢种对连铸板坯轻压下效率的影响规律.结果表明:压下效率与板坯宽度,厚度呈线性增加关系,板坯宽度每增加15%,压下效率增加约4%;板坯厚度增加15%,压下效率增加约32%;钢种的两相区温度宽度越小,压下效率越高;板坯宽度与钢种对压下效率的影响较小,板坯厚度对压下效率的影响大.关键词:连铸板坯......
liquidus and solidus. The higher Mn/Fe mass ratio results in the lower Fe content in the retained alloy, during which Mn is also consumed and settled at the bottom of the melt as solid Fe-rich... with the decrease of the temperature in the interval of liquidus and solidus. When m(Mn)/m(Fe)=0.5 in Fig. 2(a), the equilibrium concentration of Fe was decreased from 1.05% to 0.72% at 600 °C in the liquid phase......
of 60% was used by hot working at 300 °C. After pre-deformation, the samples were heated to a temperature above the solidus and below the liquidus point and maintained in the isothermal conditions... is a function of temperature in the range between solidus and liquidus. The research, which has been carried out in recent years, has proved that deformation of materials with the presence of a liquid phase......
between liquidus and solidus, the primary-Al grains ripen further and become more spherical, which is favorable to the semi-solid forming of AlSi7Mg alloy. Key words: AlSi7Mg alloy; semi-solid alloy... and solidus temperatures were determined to be 615 and 564 °C, respectively, and the optimum temperature for EPM was 720 °C. Table 1 Chemical composition of AlSi7Mg alloy(mass fraction, %) In order......
