What is the relationship between grain size and titer?5 answersThe relationship between grain size and titer is multifaceted. Larger grain sizes generally lead to lower strength in materials, especially in the low-temperature brittle regime. However, in the plastic flow regime, smaller grain sizes tend to result in weaker materials. Studies have shown that grain size has a significant impact on rock strength, with yield stress and hardening modulus following a Hall-Petch type relationship across various pressure and temperature conditions. Additionally, in the nanocrystalline regime, the effect of grain size on the yield stress of metals has been extensively studied, with predictions showing a gradual decrease in slope as grain size decreases, ultimately approaching the flow stress of grain boundaries. These findings highlight the intricate interplay between grain size and material properties, impacting strength and deformation characteristics.
How does grain size affect metal contamination?5 answersGrain size significantly influences metal contamination in various environmental settings. Smaller sediment fractions tend to contain higher concentrations of trace metals due to their larger specific surface area, with clay/silt particles (<0.063 mm) being the primary carriers of trace elements. Studies on contaminated urban soils revealed that grain size distribution (GSD) impacts the efficiency of immobilizing toxic heavy metals like cadmium and nickel, with finer particles affecting the immobilization process. Research on sediments from the Nakdong River highlighted that sites with higher proportions of fine sediments exhibited elevated metal concentrations, particularly cadmium, emphasizing the role of grain size in metal accumulation. Additionally, investigations on Kazipalli Lake demonstrated that sediment grain size played a crucial role in controlling the distribution of heavy metals, showcasing the importance of grain size in metal contamination patterns.

How can grain size be controlled to improve the formability of steel?5 answersGrain size can be controlled to improve the formability of steel through various methods. One approach is to refine the grain size through grain boundary design. This can be achieved by controlling the chemical composition and steel processing parameters, such as hot rolling and coil cooling parameters, cold reduction, and annealing. Another method is to promote the activation of tensile twins, which can enhance formability. Increasing the grain size can promote the activation of tensile twins, leading to an increase in the work hardening coefficient and a decrease in stress concentration on grain boundaries. However, it is important to note that there is an optimal grain size for formability, as coarser grain sizes can lead to a deterioration in formability due to the change in grain orientations.
What is the optimal grain size for an electrode material?3 answersThe optimal grain size for an electrode material depends on the specific application. For a positive electrode material, a grain size of 10-100 nm or a surface area per unit mass of 10-20 m^2/g is recommended to improve charging and discharging rates and capacity. On the other hand, for an electrode material with low resistance and band conduction properties, an average grain diameter of not more than 50 μm and an activation energy of band conduction not less than 0.20 eV are desired. For a negative electrode material, a small-grain size of 6-13 μm is preferred to achieve high capacity and good rate properties. Additionally, an electrode material with an average particle size of 0.5-100 μm and a volume density of 50-80% is effective in improving conductivity and supporting a carbonaceous film. Therefore, the optimal grain size for an electrode material varies depending on the specific requirements of the application.
How to calculate grain size from ASTM Grainsize number?2 answersGrain size can be calculated from ASTM Grainsize number using various methods. One method is the planimetric method, which uses a circular test pattern developed by Albert Sauveur and defined by Jay Zeffries, or a rectangular test pattern and a modified counting method by Sarkis Saltykov. Another method is the laser ultrasonic technique, which uses the generation and detection of ultrasonic waves by a pulsed laser and a laser interferometer. Additionally, the intercept method can be used, which involves measuring the intercept length of grains. There are also methods for analyzing grain size data obtained from 2D image acquisition, such as optical microscopy and SEM-EBSD, using scripts like GrainSizeTools. Furthermore, a new polyhedral grain model has been developed to correct systematic errors in converting 2D or 1D grain sizes to 3D.
