Abstract:
A special heat treatment process was used to separate the microstructural parameters, mainly grain size and lamellar spacing. The strengthening effect of grain size and lamellar spacing on fully lamellar alloy has been studied. The result reveals that the yield strength increases with decreasing grain size and lamellar spacing. A model of yield strength is proposed to explain the strengthening effect of grain size and lamellar spacing:
