Abstract
Compressive surface stresses were formed in hot‐pressed Al2O3 by quenching. Flexural strength was improved substantially, up to a maximum of 223,000 psi. The variation of strength with grain size of the quenched bodies was similar to that of the unquenched material, but the strengths were shifted to higher values. The presence of a glassy intergranular phase is not necessary to obtain compressive surface stresses by quenching.This publication has 5 references indexed in Scilit:
