Besides the DINL, the segregation of B atoms in the grain boundary is also an essential factor for toughening the CCIMA. It is reported that element B is less electronegative compared to base alloy43. Thus, B atoms prefer to share electrons with the metal atoms (i.e., formation of homop...

This approach allows us to factor the definition of the continuous algebra structure [105,112,117] on D in three similar steps. DEFINITION 7.7 (ST-preorder) ⊑ is the least binary relation over ST(Act) such that the following conditions are satisfied if S1 ⊑ S2: (1) if 〈a,S′1...

Recent advances in the study of triangle-free processes [5], [16] have led to further improvements in these bounds, so that r(Kn,K3) is now known up to an asymptotic factor of 4. The main off-diagonal problem that we treat in the ordered case is that of determining the ordered ...
Because the grinding temperature is high when grinding using conventional disordered grinding wheels, the grinding quality improvement is limited when using single abrasive ordered grinding wheels, and the wheel preparation process is complex and costly
