Abstract:
Biomedical alloys Ti-6Al 7Nb was taken and its Vickers Micro hardness behavior was investigated at three different loads 300 gm, 500 gm and 1000 gm and four different dwell time i-e 10s, 20s, 25s and 30s. The average VHN number for the alloy was between 350 and 358. These values for the said alloy agreed well with the reported hardness of the enamel of human molar teeth. Further, the two way ANOVA tests revealed that the dwell time had no significant effect over the hardness value therefore a dwell time of 10 seconds is sufficient. However, the hardness values showed variation with the load. Tukey tests revealed that for Ti-6Al 7Nb the difference in hardness values for 300 gm and 500 gm load at various dwell time were not statistically significant, however the hardness values for both the loads differed than that of 1000 gm applied load. The traditional Meyer's law was used to analyze the load dependence of the hardness and it pointed positively towards the indentation size effect for both the alloys.
