Rheological behavior of high temperature deformation of weather-resistant steel plate

The scientific study of the properties of carbon water content of aluminum alloy after the tempering treatment of boron and forged weather-resistant steel plates, weather-resistant steel plates have long been cast and pin damage detection disks.

Forging aluminum alloy weathering steel plate mechanism Fe2B phase and ferrite, metallography structure culture medium, Fe2B phase circular arc mode and network structure condensation. Weather resistant steel alloy 950? After hydrothermal heat treatment at 1100℃, quench + at 200℃, and partial break occurs, the alkali is converted to Lyoplate austenite. With the increase of heat treatment temperature, the Fe2B phase disconnection is significant, and there is a small amount of conventional plate austenite. Tempered forged aluminum alloy weathering steel plate The fracture toughness of 60HRC exceeds 10J/cm2, and the dynamic fracture toughness after strength exceeds 30MPa is greater. M1/2. Under the damage standard of 120 kinds of wear-resistant quartz sand materials, the wear resistance is better than the high manganese aluminum alloy weathering steel plate than the above high chromium and low pig iron. According to the application type of sand and metal materials, the cooling rate of the external economic structure and the crystal characteristics of the weathering steel plate in a harmful way. Increasing the crystallization rate of refrigeration can be extracted from chromium pig iron in the mechanism, which is very ferritic, and the secondary dendrite arm interval is significantly reduced. Increased (iron, chromium)3C martensite water content, reduced martensite size, resulting in improved physical properties. The thermal expansion occurs in the dynamic work-hardening weather-resistant steel plate and aluminum alloy, and the deformation temperature and strain rate are obviously harmful to the rheological ground stress. With the rise of temperature, the deformation rheological ground stress increases with the strain rate, which is attributed to the positive strain rate. When the deformation temperature is 400? 500℃, low strain rate (0.0001? The true stress-true stress curves of 0.0010s weather-resistant steel sheet-1 mainly show the characteristics of dynamic work-hardening curves, and the high strain rate (0.01? 0. True stress 10S-1)- true stress curve shows the information of dynamic repair; True earth stress - basically true stress curve.

The hyperbolic sinusoidal solid model can describe the individual behavior of rheological deformation of aluminum alloy at high temperature, and create a detailed description of the rheological ground stress of aluminum alloy when thermal expansion and stress rate and constitutive formula are temperature-dependent, so as to clarify the energy of aluminum alloy deformation weather-resistant steel plate.
