Comparison Between the Properties of Al-TiC and Al-(TiC+Fe3C+Fe2Ti+Fe) Composites

This paper aims to study the efficacy of (TiC+Fe3C+Fe2Ti+Fe) powder mixture produced by a new synthesis technique utilizing a cheap source of Fe-Ti and C (in terms of wear resistance and hardness). The powder product was used as reinforcement in Al matrix. Composites were produced by mixing 20 wt% of the reinforcing powder and 80 wt% of Al followed by 10 ton cold pressing and sintering for 2 h at 500 A degrees C. The composites reinforced with the synthesized powders were compared with the composites produced using pure TiC as reinforcement material. Wear rate and hardness of composites using synthesized TiC mixture as the reinforcement material were found to be very close to that produced with pure TiC. The results of wear and hardness thus confirm that the synthesized powders containing TiC, Fe3C, Fe2Ti, and Fe can replace pure TiC in aluminum matrix composite applications

Design and develop a nondestructive infrared spectroscopy instrument for assessment of mango (mangifera indica) quality

A portable infrared spectroscopy system has been designed and developed for assessment of quality of mango fruit. This paper describes the design and development of a fruit quality grading device using reflectance mode optical sensor. The experiment was conducted to obtain the best results from the system and the device was correlated according to the measured output. In the experiment, several samples of mango fruits have been monitored for six days to study the relation how fruit quality increases with time as fruit ripens. Between the unripe mango fruit and the ripest one, a range of 3.5 V to 4.2 V was measured by the developed system. The rate of quality increase was calculated as an average of 6.7 mV per day. These results were used to correlate the final hardware and software development of the device. The results demonstrate that, portable near infrared spectroscopy is feasible for evaluating mango quality non-destructively
