Study on Finite Element Analysis and Experimental Verification on Annealing of Diffusion Bonded Mg/Al Alloys

With the rapid growth of the transport, aerospace, and defence industries, due to their low densities, high specific strengths, excellent casting ability, and outstanding vibrational energy absorption, magnesium alloys have received increasing attention. The finite element method for analysing the effect of annealing temperatures on residual stress in the diffusion zone of AZ31 Mg and…

A Detailed and Comparative Study on Conventional Sintering with Microwave Sintering and Vacuum Sintering of Y2O3-Al2O3-ZrO2 Ceramics

This chapter focused on comparative studies on conventional, microwave and vacuum sintering of alumina-added stabilised zirconia yttria (YSZ). When energy and time savings are involved, microwave sintering has been found to be the most effective sintering technique. In contrast to the conventionally sintered ones, microwave and vacuum sintered specimens display improved densification at lower temperatures.…

Temperature and Elementary Carriers of Heat

The experimentally determined temperature of a substance is a comparative value relative to the extensive property of another system (thermometers, thermocouples, etc.) taken as the initial measurement standard or reference point. Therefore, the concept of temperature, which we face at first glance seems to be a very simple value, but in fact it is a…
