Abstract

Microparts are commonly defined as parts or structures with at least two dimensions in the sub-millimeter range which are used extensively in electronics and micromechanical products. This paper presents recent findings on micro-extrusion experiments and analysis results of brass (Cu/Zn: 70/30). We find that microstructure of brass affects the final deformed pin geometry and frictional force. When an extruded pin has only several grains across its dimension, the pin tends to bend arbitrary. Meanwhile, the friction force experienced a lower friction coefficient when size reduces.
