Landmarks in Mechanical Engineering (History of Technology)

The e-book describes, and the place attainable illustrates, ancient mechanical engineering landmarks, representing the accomplishments of mechanical engineers during the last 250 years-from the steam engine of Thomas Newcomen (1712), which introduced the commercial Revolution, to the Saturn V rocket (1967). a few of them are recognizable to us all, resembling Xerography, Sikorsky's helicopter, and Disneyland's monorail.

Investigations on Microstructure and Mechanical Properties of the Cu/Pb-free Solder Joint Interfaces

This thesis provides a chain of mechanical try out equipment and comprehensively investigates the deformation and harm habit of Cu/Pb-free solder joints below varied loading stipulations. The fracture habit of Pb-free joint interfaces brought on by way of tension, deformation of solder and substrate are proven, the shear fracture power of the Cu6Sn5 IMC is measured experimentally for the 1st time, and the dynamic harm procedure and microstructure evolution habit of Pb-free solder joints are published intuitively.

I-V and I-P characteristics of the cube at 500°C, 550'C and 600'C when the anode gas was 150ccm H2. Figure 8 shows the I-V and I-P characteristics of the cube at 600°C. The anode gas was humidified 100ccmH~+100ccmN~ and the cathode gas was changed to various flow rates. The OCV was higher than the previous case (1 50ccmH2), because the flow rate of the anode gas was less and then the heating value was less. When the cathode gas was 450ccmO~+l800ccmN~, the anode gas were 625'C and 603'C, temperatures for 15OccmH2 and 100ccmH~+100ccmN~ respectively.

The coated t i h s were dried in air, and co-sintered at 1400 OC for 1 h in air. The anode tubes with electrolyte were, again, dip-coated with a cathode sluny. which uas prepared in the same manner using Lw&OJCoOzFeOs01, (LSCF) (Seimi Chemical. co.. ), the GDC powder, and organic ingredients. After dip-coated, the tubes bere dried and sintered at 1000 'C for 1 h in air to complete a cell. 8 mm. The appearance of complete cells was shown in Fig. 1(b). The microstructure of the tubular cells was observed by using SEM (JEOL.
