In this research a novel concept, quenching and tempering-associated partitioning (Q–T &
P), has been proposed by a new alloy design with a 3.5 wt.% aluminium addition, in which
the quenching temperature is designed at ambient temperature and the initial phase
constitution is adjusted through the Ms temperature by alloy design and intercritical
annealing. In addition, with regard to the partitioning achieved by the simple quenching and
tempering heat treatment, the new Q–T & P is approximate 5% lighter than conventional …
