Answer
An alloy whose mechanical strength is improved by precipitation hardening or a martensitic transformation, both of which involve specific heat-treating procedures, is a heat-treatable alloy.
An alloy whose mechanical strength is not improved by precipitation hardening is a non-heat-treatable alloy.
