Metal matrix composites of Aluminium are finding increasing applications across a wide range of industries, including the automotive and aerospace industries, amongst others. When a third constituent is added to the metal matrix, the production of the hybrid compound commences. This body of work presents the findings of an investigation into the surface roughness properties of hybrid aluminum metal matrix (Al6061-SiC-Al2O3) composites. Some exper- imental investigations were carried out using a lathe. The stir casting method is a technique employed in the field of liquid metallurgy. In this technique, the base matrix was infused with 4, 8, and 12 percent by weight of SiC and Al2O3 particles, respectively. This allowed for the production of composites. The end-result cast composites were handled with a great deal of care and atten- tion to detail. The parameters such as feed rate, cutting speed, and depth of cut that are known to influence surface roughness were investigated. The findings of the study demonstrated that an increase in feed rate leads to a rise in sur- face roughness, but an increase in cutting speed leads to a decrease in surface roughness.

The first part discusses the introduction of the topic, followed by the different types of online payments. The research discusses the present condition of e- commerce, and the online payment mechanisms used in Delhi NCR. The study segment employs a questionnaire survey to investigate several types of client attitudes concerning online payments. The questionnaire was filled out by 50 respondents from Delhi NCR. The statistical test used was ANOVA. The main objectives of the study were to understand whether there is a difference between respondents’ gender & the frequency of online payments, the pros & cons of online payments & challenges of online payments. Also, the researcher tries to understand whether there is difference between respondents’ age & the fre- quency of online payments, the pros & cons of online payments & challenges of online payments. The findings concluded that there is no significant asso- ciation between the gender of the respondent & other parameters, whereas, in the case of the age of the respondent, a significant association has been seen.
