抄録
Elastic-plastic fracture toughness was investigated by using electric potential (EP) and acoustic emission (AE) methods for cast irons with various types of graphite morphology including flake, CV and spheroidal and with various amounts of pearlite in matrix structure. Jin(AE) and Jin(EP) evaluated from the deflection points of AE event count and electric potential curves, and Jin(R) from cross point of blunting line and R curve in J-Δa(EP) plot are related by Jin(R)=1.34 Jin(AE)=1.34Jin(EP). And Jin(R) can be defined as JIC in cast irons used. JIC is expressed in regression equation with relation to nodularity n[%] and pearlite content in matrix P[%] as follows.</br> JIC=16.614+0.500·n[%]−0.060·P[%]−0.004·n[%]·P[%]
