I am doing my university project about the relation between vickers and rockwell hardness. I know that there is not a mathematical relation but I need to find a good approximation. I have practice both tests in more than 50 specimens (HV70-HV950) and I have more than 300 (HV1,HR1),(HV2,HR2),... points. Any idea how to find the relation? I have done some graphics and got their ecuation with excel but how can I know which is the best one, because I have more than seven different equations (logaritmic, polinomical, exponentials,...). Sorry about my english thanks(adsbygoogle = window.adsbygoogle || []).push({});
