Improved measurement of thermal effects on microstructureThe objectives were to introduce a simple methodology which could be used to replace the time-consuming and expensive conventional methods of metallographic and quantitative analysis of thermal treatment effect on microstructure. Metallurgical analysis continually calls for the evaluation of thermal treatment effects on microstructure. This commonly demands metallographic sample preparation and microscopic examination, which are time absorbing and costly. These drawbacks are burdensome when large numbers of samples must be levied fast. Mechanical testing can sometimes be substituted, but sample size and shape frequently make these methods impractical. The experiment described here is ideal for the microstructural evaluation of lamp filaments and other wire samples such as copper wire which can be conveniently coiled.
