概要:

金沢大学理工研究域機械工学系<br />The influence of dispersions of particles on the recrystallization behavior has been examined in industrially processed specimens of a Cu-Fe-P alloy(CDA194). The specimens are produced through the steps of hot roll … ing, cold rolling, aging and final cold rolling. The γ→α martensitic transformation of small coherent γ-Fe precipitate particles which form on decreasing temperature during hot rolling is induced by subsequent cold rolling. Aging following the cold rolling produces fine γ-Fe particles, which are transformed to α-Fe by final cold rolling. The nucleation of recrystallization occurs predominantly at coarse Fe_3P particles, observed after the hot rolling, larger than about 1μm in diameter. A denser dispersion of smaller α-Fe particles shows a larger retarding effect on grain-boundary migration. A specimen with smaller α-Fe and smaller Fe_3P particles has a higher heat resistance and a higher strength. 続きを見る
