Before testing by the tester, the surface of each tablet was ground by # 120, # 240, # 400, and # 600 carborundum sandpaper in series. The applied load during testing was 5 kgf, and the loading time was 10 sec. The hardness of each tablet was measured at seven different locations, and the average value of the medium five data points was used to determine the hardness. The results were shown in Table 1. [0023] Table 1 shows the hardness of alloys No. 1 to No. 20, in either as-cast state or heat-treated state. It can be seen that the alloy hardness changes with element number and composition. Generally speaking, more major elements may yield higher hardness, and adding minor element boron may further increase the hardness. The hardnesses of the alloys No. 2, 6, 16, 18 and 19 show a small decrease by heat treatment. However, those of others may be unchanged or increased. In Table 1, the hardness ranges from Hv590 to Hv890. Fully quenching-hardened carbon steels and alloy steels, with 0.35% to 1.0% carbon, provide a similar hardness range. On the other hand, the hardness of quartz is Docsity.com
