| Abstract: | The strength of diamond powders of grit size 125/100 μm synthesized in the Mg-Zn-B-C system (reaction mixtures having different
boron concentrations) has been investigated. It has been shown that the distribution of strength by fracture load is correctly
described by the Weibull function. The strength index of diamond powders and confidence intervals has been defined. It has
been found that the strength index dependence on boron concentration in the range from 1 to 40 at % is described by the function
having the minimum at 20%. |
