摘要: ABSTRACT The effect of grain boundary segregation on creep intergranular fracture at high temperatures has been studied alpha iron-tin alloy in which remarkable tin, hardening and embrittlement due to the were previously observed. structure also for polycrystalline specimens contained boundaries whose character had predetermined by selected area electron channeling pattern (SACP) technique. Extraordinary migration was observed accompanying sliding during creep. Extensive took place irregularities boundaries. It made clear that enhances alloy. found ransom angle more preferentially than coincidence or slightly off-coincidence
