Abstract

The mechanical properties hardness, tensile strength and fracture toughness of (Fe100−x Mx )83B17 glasses were measured for different alloying con en s and heat treatments. In the as quenched state the hardness is influenced mainly by changes in the metal-metalloid bonding. The fracture toughness is dependent on the alloying elements as well as the actual state of the glass. Heat treatment of the glass thus hardly influences the hardness whereas the toughness decreases strongly and significant changes in the fracture surface occur. Calorimetric observations suggest that structural relaxation is the primary reason for this behaviour although some effect of annealing out of internal stresses must be present.
