The Structure-Property Relationship of Cold-Drawn 1010 Steel Tubing

Sullivan, Charles Kenneth 15 August 2014 (has links)
This study focuses on the evolving microstructure and its associated mechanical properties during each step of a seven step manufacturing process for 1010 steel tubing. For the microstructural analysis, we employed optical microscopy to quantify the ferrite grain size and pearlite grain size at each material step. To determine the mechanical properties, we used a Vickers hardness indenter and performed both tension and compression tests at varying strain rates and temperatures. Mechanical tests results indicate decreasing strength with increasing grain size, agreeing with the Hall-Petch relation and were used to correlate hardness and yield strength with grain size. Additionally, tensile and compression tests were performed at different strain rates to examine the effect of microstructural features on the mechanical properties of the steel tubing. Understanding the structure/property relationships of 1010 steel tubing during different processing conditions allows tubing to be manufactured more efficiently with desirable mechanical properties.
