Non-destructive investigations of intermetallic compounds are undertaken, on compact metallographic specimens by one of the following methods:
1. X-ray structure analysis can be used with great success particularly in the investigation of two-phase alloys where the crystal type can be only determined crystallographically.
2. Laser microspectral analysis yields qualitative results only. The quantitative concentrations of the individual elements cannot be determined.
3. On account of its unpretentious and easily accessible requirements metallographic analysis is one of the most widely used methods of identifying intermetallic compounds in aluminium alloys, ......
4, Microprobe analysis offers the possibility of Conducting qualitative and quantitative investigations of intermetallic compounds, ……
金属互化物的无损鉴定适用于块状金相试样，其方法不外下列四种：
1. X 射线结构分析  此法使用得十分成功，尤其适合于鉴定那些只能从结晶学上确定其晶体类型的两相合金。
2. 激光显微光谱分析   此法只能获得定性的结果，而不能测定各个元素的定量浓度。
3. 金相分析  由于对分析的要求是简单和易于触及，此法是鉴定铝合金中金属互化物的一种最广泛使用的方法。……    
4. 电子探针微量分析 此法能够进行金属互化物的定性与定量检验。……
(从每段中提出一个关键词组作为小标题，更显得眉目清楚。）
