Clusters of galaxies are thought to form by accretion of galaxies along the cosmic filaments, and merging of clusters formed earlier. Observations and hydrodynamic simulations show the strong effects of mergers on physical conditions of Intra Cluster Mediumn (ICM). In this work, we investigate five relatively nearby Abell clusters; A3705 (z= 0.089), A2440 (z= 0.090), A2933 (z= 0.092), A3888 (z= 0.152) and A115 (z= 0.193). Temperature and metal abundance maps are created by wavelet algorithms. Peculiar regions are spectrally studied and large scale deviations are observed. Abell 2440, Abell 2933 and Abell 115 are found to be in ongoing merging phase. One of them, Abell 3888, is found to be in a dynamical state with a possible merging of galaxy groups. Only Abell 3705 is found not to show any merging activity. Our studies are consantrated on individual portions (regions) extensively, thus the X-ray analyses done in this work for their X-ray spectra and temperature maps cover these individual portions, extensively. In this study, Abell 3705, Abell 2440, Abell 2933 and Abell 3888 are studied in a rather extensive way compared to the early work done on these clusters for the first time.
