Fixed Abrasive Lapping and Polishing of Hard Brittle Materials

Key Engineering Materials, 2010
Fixed abrasive lapping and polishing (FALP) is a new machining technology and was adopted to manufacture hard brittle materials and obtain the high productivity because of fixed abrasive. The preparation process of fixed abrasive pad (FAP) was described. FALP of K9 glass, mobile panel glass and Si were investigated with fixed 5-10 µm diamond abrasives.

Theoretical model of hardness anisotropy in brittle materials

Journal of Applied Physics, 2012
Anisotropy is prominent in the hardness test of single crystals. However, the anisotropic nature is not demonstrated quantitatively in previous hardness model. In this work, it is found that the electron transition energy per unit volume in the glide region and the orientation of glide region play critical roles in determining hardness value and ...

Experimental Study of Precision Polishing of Hard and Brittle Material

Key Engineering Materials, 2007
The application of hard and brittle materials become wider and wider because its self-characteristics. It is used widely in finish machining of products, such as memory record device, information products, precision instrument, etc. Traditional grinding-polishing methods have not suited for precision machining requirements of hard and brittle materials.

Ductile to brittle transition in ultra-micro-grinding (UMG) of hard brittle crystal material

The International Journal of Advanced Manufacturing Technology, 2018
In this study, ductile to brittle transition in ultra-micro-grinding (UMG) of hard brittle material is investigated. The characteristics of UMG process are studied, and differences between UMG and micro-grinding (MG) are investigated. The grain penetration depth considering rotary deviation is calculated, grain invalid cutting phenomenon is discussed ...

HARDNESS TEST FOR MEASUREMENT OF FRACTURE TOUGHNES OF BRITTLE MATERIALS

2007
In the paper a new method for the measurment of fracture toughness during hardness test is described. Thise technigues is based on the observation that some materials will have fracture when indented with a certain critical load, tipical for Vickers hardness test. The measurment results are given for welding steel and compared vith scharpy test.
