“destabilization” of this microstructure and the consequent recrystallization of the Sn phase due to thermal stress under thermal shock conditions pose considerable challenges to the reliability testing of solder joints [ 14 ]. Under the effect of high temperature

/s. Research of lunar soil particles confirms the shock origin of matter transformation. Processes of shock melting and subsequent recrystallization with a cooling rate in the range of at least 0.1 to 1 °C/s are possible on lunar surface. Physical and chemical

dynamic recrystallization. A significant reduction of twin boundaries fraction in the stir zone was observed in comparison to the base metal. Keller et al. studied the influence of SPS conditions on the sintering and functional properties of an ultra

The pressing of equal channel angular pressing - parallel channel process has an effect on microstructure and mechanical properties of the composite materials. Finite element has been used for conducting pressure effect through parallel channel for knowing distribution effect pressing. The materials AA1070 and AA6061 powder matrix composite with Al2O3 nano fiber were used as reinforcement. Mechanical properties and scanning electron microscope were observed in room temperature pressure and in case where the temperatures were higher than recrystallization value. Both results were compared to determine the effectiveness of pressure on each process. The characterization of aluminum composites on the aspects and phenomena of the distribution of pressing effect on hot and cold conditions treasured by finite elements will be explained in this paper.

firmness ( Ben Haj Said et al., 2016 ). However, it is well known that natural products also undergo quality changes and losses throughout subsequent storage in the frozen state. Physical changes, such as recrystallisation of ice, can occur during storage

digestion. Components of starch, amylose, and amylopectin are responsible for the short-term and long-term retrogradation, respectively. Crystalline amylose was found to be the nucleus for amylopectin recrystallisation in long-term processes ( Keetels et al
