The carbon content in the spearhead core was close to the 0.8% eutectoid
Due to the addition of [beta] eutectoid
element tungsten and neutral element stannum, the alloy possesses excellent mechanical performance combining strength, persistence and stability at the service temperature of 723-823 K.
Pearlite forms after eutectoid
point when single phase austenite splits into two phases, cementite and ferrite.
The additional consideration of segregation effects of alloying elements allows for the accurate prediction of ferrite and pearlite growth during the eutectoid
In addition, copper shifts the eutectoid
composition towards lower
The microenvironment at the rear of the plate had promoted selective attack on the copper-rich a-phase, which has higher concentrations of arsenic and zinc than the ([alpha]+[delta]) eutectoid
. Thus it was established that one of the past microenvironments of the plate was a highly oxygenated, salt-laden moist environment.
