The processing of aluminum composites plays a significant factor in develop the usage of such composites. The analysis of microstructure of the deformed composites specimens gives a degree of understanding of the effect of deformation process conditions. In recent years, the advent of high-speed, general-purpose, digital computers and vision systems has made image analysis easier and more flexible. Computer vision technology has maintained tremendous vitality in many fields. One of the common techniques employed by computer vision is the texture features techniques. Texture is related to qualitative properties of surfaces, but due to its complexity and great variety, there exists neither a unique definition of texture nor an accepted computational representation of it. Image texture analysis is useful in a variety of applications and has been a subject of intense study by many researchers. In the present work, the effect of forming temperature on the forming behavior of aluminum and aluminum reinforced by 10 wt% SiC was studied by using image texture features after using the compression test which was done at an elevated temperature range of 300–550 °C and a constant strain rate of 0.024 s−1. The current study used a computer vision technique with Sum and Difference Histogram Matrices (GLSDM) to investigate the forming temperature of aluminum and aluminum/silicon carbide (Al and Al/Sic). The relationships between each GLSDM texture feature and the operation temperatures are discussed and the correlation coefficients are obtained. The results showed that some texture features have high correlation coefficients with high sensitivity to changes in temperature. |
