Procedure

According to the experiment, Superhard Steel™ alloy SHS717, having a structure of Fe52.3Mn2Cr19Mo2.5W1.7B16C4Si2.5, was melted and additions of aluminum and boron were made at a 1 to 12 ratio to provide aluminum boride in the alloy at 10, 15, 20, and 63 atomic percent. The alloy was subsequently formed into ingots and allowed to cool. The resultant harnesses of these modified alloys, measured at a load of 100 kg/mm2 and 300 kg/mm2, are given in Table 3. Note that all hardness indentations are reported as an average of a minimum of 5 indentations.
