The mechanical strength of grain boundaries was calculated by the research team to find out the way each of them influenced the other.

研究者们计算了每个晶界的力学强度来探寻它们之间相互影响的方式。

With the densification, material density and mechanical properties are promoted distinctly, the boundaries and cavities in the deposits are welded and the microstructure reaches even.

在致密化加工过程中 ，材料的密度和力学性能明显提高 ，沉积坯中的界面和孔洞明显愈合 ，材料的显微组织趋于均匀。
