除基体与γ'相外,在低成本粉末锻件第三批试样中发现MC型、M23C6型碳化物、氧化物等多种第二相,通过TEM衍射花样及高分辨像晶面间距比对进行了分析确定
In addition to matrix and γ' phase, MC-type, M23C6-type carbide, oxide were found in the third batch of samples of low-cost powder forgings, which were analyzed and determined by TEM diffraction pattern and high-resolution image interplanar spacing comparison.
