The formation of bonds in vitrified abrasive wheels is treated as a transient viscous flow process to determine if particles in a wheel are in direct contact. Two initially separated solid spheres are found to be drawn together by surface tension, so that particles are indeed in contact during a typical firing cycle. Because of this interparticle contact, wheels will be stiffer when loaded in compression, when the high‐elastic‐modulus particle carries the load, than when in tension, when the low‐modulus bond carries the load. The occurrence of interparticle contact explains several observations on wheel performance.
