Keywords： bulk metallic glass

A Fe61Co1oZr5W4B20 bulk metallic glass (BMG) with a diameter of 2 mm was prepared by using copper mould suction casting.The X-ray diffraction (XRD),differential scanning calorimetry (DSC),micro-hardness and compression tests were adopted to investigate the structure,thermal stability,especially,the effect of heat treatment on the micro-hardness and compression strength of this BMG.The BMG exhibits micro-hardness of about 1 207 Hv and compression fracture strength of about 1 707.6 MPa.After being annealed below the onset of crystallization temperature,the micro-hardness almost keeps constant.But after being annealed above the peak of crystallization temperature,the micro-hardness increases firstly and then declines gradually with the elongation of annealing time.However,annealed for the same period of time,the micro-hardness will increase with the rise of annealing temperature,while the compression fracture strength will apparently decrease.
