Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

One of a major problem in electro discharge machining is the formation of the recast layer, which causes hard, brittle and micro cracks layer from the high temperature during machining. This article was focused on the method of reduces the thickness of layer damage of high speed steel work material by using a composite tool from copper-silver instead of copper tool. An experiment was carried out using a copper – silver composite tool and pure copper tool. The machining conditions included the use of the pulse current and pulse on time as input parameters. The morphology, microstructure of white layer was characterized by scanning electron microscopy. The results showed that the surface quality of high-speed steel after EDM with copper –silver composite electrode and copper electrode are dissimilar. In this case, EDM using composite electrode the recast layer thickness from pure copper electrode were reduced from the maximum value 14.56 μ m to 3.28 μ m moreover experiments showed improvement of micro hardness value from (297.1 to 193.6) Vickers of surface layer compared to the pure copper electrode
The tensile behaviour of two types of asphalt films confined between aggregates particles as adhered stub investigated. Axial finger aggregate samples fabricated using a modified prototype set up allowing construction of micro-scale thin films of asphalt's binder and digital visualization of failure phenomena stages. The effect of temperature (20°C and 10°C), binder type (neat and polymer modified), adhered type (two types of aggregate), and water conditioning were investigated sequentially. The results show that water sensitivity towards aggregate-binder combinations displayed reduced properties in the micro- scale when water conditioned. The tensile strength of the thin film of asphalt increases linearly with the binder film thickness to a maximum value and then it reduces with increasing test temperature and deformation rate. The average strength of the PMA is greater than pure asphalt binder due to the enhanced adhesion properties between asphalt binders with the aggregate particles. This increase requires higher external energy for failure. So the average stiffness reduction and average damage parameter is less than pure binder. The average elastic modulus and average hardness modulus for PMA is greater than unmodified asphalt binder
