An investigation on the fracture phenomena of (α+β) brass, polycrystalline alloys, has been conducted using the scanning electron microscope(S.E.M.). The as-rolled alloys (starting material) were subjected to different conditions of annealing. Then, tensile tests were carried out at room temperature on three categories of specimens being; (i) as-rolled, (ii) an-nealed at 923K for 86.4ks, and (iii) annealed at 873K for 2 Ms plus 1.4 Ms at 800k. All types of specimens showed ductile fracture. Fracture surfaces were then observed by the S.E.M. on both the macro-and micro-scopic scales. All specimens exhibited a transgranular mode of fracture. Fracture surfaces revealed some changes in the pattern observed on each phase due to annealing conditions. Dimple pattern was observed on the (β-phase, although different dimple size existed for different types of specimens. On the other hand, on the α-phase, fracture surface, smooth ripple pattern was observed, additionally, large dimples were detected on the α-surface. In essence, the present results not only confirmed previous results on single-and bi-crystals of brass but also throw the light on more details about the fracture phenomena of brass which was not reported before.
