W元素对Laves相形核化学驱动力的影响最大。理论上在650℃下超过1.05 wt.%的W元素就可以实现Laves相的形核,这约为G115钢中W设计含量的1/3。
W element has the greatest influence on the chemical driving force of Laves phase nucleation. Theoretically, more than 1.05 wt.% of W element at 650℃ can achieve the nucleation of Laves phase, which is about 1/3 of the design content of W in G115 steel.
