A further increase in hardening which is possible to achieve during the tempering cycle, due to the sub-microscopic precipitation of fine alloycarbide‘ particles. In some alloys, where a phase transformation‘ does not take place, secondary hardening may be the only method by which the alloy can be hardened.
