两磨面拼合技术又称双表面配合分析法,主要是利用两个互成90°角的邻近磨面的合成金相照片来显示合金中相和组织的立体(三维)形态。国外六十年代即已普遍采用,而国内的报导较少。现将此法介绍如下。试样的制备在制样时防止倒角是一个关键,必须采取下列措施: 1 试样最好做成10×10×15毫米左右的长方体,然后夹入具有HRC40～50的65Mn钢制成的夹具
Two grinding surface flattening technique, also known as double-surface matching analysis method, mainly uses two synthetic metallographic pictures of two adjacent grinding surfaces mutually forming an angle of 90 ° to show the three-dimensional (three-dimensional) morphology of the phase and the structure in the alloy. Foreign 60’s has been widely used, while less domestic coverage. Now this method is as follows. Preparation of Specimen Prevents chamfering during sample preparation is a key issue. The following measures must be taken: 1. The specimen is preferably made in the shape of a rectangular parallelepiped with dimensions of 10 × 10 × 15 mm and then clamped into 65Mn steel with HRC 40-50 Fixture
