4th Party Cyber Logistics for Air Cargois discussed. When the tempering temperature is increased, a large amount of nitrides form in the matrix. The impact energy is greatly increased. The ductile-brittle transition temperature also decreases when the tempering temperature is increased from 650 to 750 °C. The nitride precipitation while

The toughness of the steel decreases greatly when tempered at 450–600 °C, the hardness reaches a maximum and the steel exhibits morphology of intergranular plus quasi-cleavage fracture. The grain boundary weakening caused by the precipitation of chain-like

Geometric Model-Based 3D Face Tracking,ion can effectively exert the beneficial influence of precipitates on microstructures. In this sense, the microstructural stability of the tempered martensite is in fact the stability of precipitates during the creep. The creep stress could promote the formation of Laves phase. Many attempts have be

Learning Geometric 3D Facial Motion Model,g effects. The deformed part of the creep specimen has lower hardness than the aged part because stress can accelerate the microstructure evolution. In the final part of the chapter, the creep rupture mechanism of heat-resistant steel under different stress levels is discussed. Under conditions of h

Geometric Model-Based 3D Face Tracking,eel would increase the fraction of precipitates by increasing the volume of DSIT ferrite during deformation. In the calculation of processing maps, with the change of Zener-Hollomon value, there are three domains of different levels of workability, namely excellent workability region with equiaxed-g
