Notes: Abstract We present the phase diagrams in a 2D spin 1/2 Ising model for the triangular lattice. Using the finitecluster approximation and renormalization technique we studied a nearest-neighbour random interactions. Ferromagnetic exchange interactionsJ are considered with concentrationp and exchange interactions αJ (|α|≦1) with concentration (1-p). The phase diagrams were obtained for this model. They show re-entrant behaviour in certain ranges of the concentrationp and different α.
