Number Of Slip Systems In Fcc. 8 rows Face Centered Cubic Slip Systems FCC eg. Dislocations must move on non-closed-packed-planes such as 110 112 and 123 planes. If there are at least 5 independent slip systems the metal is ductile. There are 12 total slip systems 5 independent.
Of slip systems does not make BCC more ductile than FCC which infact has 12 slip systems because the orientation also matters. Each of the directions is common to two octahedral planes resulting in a total of 12 slip systems. Magnesium is nearest to the perfect. Presents 12 systems and includes metals like copper aluminum nickel and silver. Slip is also possible on 100 along 10 bar 1. Presents 48 slip systems and includes a wide range of metal alloys.
FCC it has a coordination number of 12 provided the ca ratio shown in fig.
Of slip systems does not make BCC more ductile than FCC which infact has 12 slip systems because the orientation also matters. Presents 12 systems and includes metals like copper aluminum nickel and silver. Presents much less BCC and FCC crystal structures. The number of independent slip systems is 12. Thus FCC metals have low yield strengths. Overall we call the slip system 111.
