WebMar 31, 2024 · The kinetic analysis showed that the grain growth of HEB phase in HEB and HEB-SiC ceramics is controlled by interface-controlled kinetics and grain-boundary pinning, respectively. The growth rate constant of HEB grains is lower than ZrB 2 , which is related to the low grain-boundary energy and the sluggish diffusion effect in dynamics … WebGrain Boundary CT Vol 118 - (Ceramic Transactions) 3rd Edition by Sakuma & Ikuhara Y & Sheppard LM (Hardcover) $133When purchased online In Stock Add to cart About this item Specifications Dimensions (Overall): 9.21 Inches (H) x 6.14 Inches (W) x 1.38 Inches (D) Weight: 2.32 Pounds Suggested Age: 22 Years and Up Number of Pages: 612
