查询词典 hexagonal system

Electroless Co-Ni-P thin film as-deposited was amorphous possessing smooth surface. The film was crystallized after heat treatment at 300℃ for 1 hour, and the surface of film was composed of "taper humps". When the film was heated, phase of Co2P deposited from the solid solution and allotropic transformation took place from hexagonal close-packed system to face-centred cubic lattice.

摘 要：化学镀Co-Ni-P薄膜镀态下为非晶态结构，表面较为平整；经300℃×1h热处理，发生了晶化转变，表面由"圆锥峰"所构成；随加热温度的提高，镀层析出了Co2P相，并发生了由密排六方结构的α-Co向面心立方结构的β-Co的同素异构转变。
