Estimating the Mechanical Properties of Diamond-Containing Composites Using the Value of the Coercive Force

We propose to estimate the mechanical characteristics of diamond-containing composites for stone-cutting wheels made of a metallic binder with a ferromagnetic component by the coercive force. For M6-14 and M6-14-1 binders, the hardness (yield stress) depends linearly on the coercive force in the range 85–100 HRB. The value of the coercive force of a diamond-containing composite rather well reproduces its structural state, which essentially depends on the composition of the binder, the original material, the manufacturing technique, and the sintering temperature of the composite. The obtained regularities enable one to determine the optimum interval of values of the coercive force for the required level of the mechanical characteristics depending on the composition of the binder.
