Abstract
Al-B alloys containing about 5% boron have been obtained by reacting potassium fluoroborate (KBF(4)) with aluminium. The parameters affecting the reaction process such as: temperature, time, mixing speed, potassium fluoroborate to aluminium weight ratio and particle size were studied. The experiments were carried out by three techniques: first by adding KBF(4) only, second by adding a mixture of KBF(4) and granular aluminium and third using mechanical alloying. The results indicate that the second technique is considered to be the best one. Microstructure examinations and X-ray diffraction tests were carried out on the produced alloys.
