Microstructure and functional properties of rock materials
网页2007年11月1日The influence of increasing complexity in the grain shape and grain boundary geometry is also reflected by properties such as the resistance to drilling penetration [11] and thermal wear. The grain boundary geometry is, however, not as complex in rock as in industrially-produced materials, and thus has less influence.
