The present work reflects the effects of trace addition copper (up to 1 wt.%) and zinc (0.5 on microstructure hardness property heat treated A356 (Al-7Si) alloy. Small amount was introduced into in both atomic form (alloy) powder (composite) its age hardening behaviour were investigated. To enhance wettability during composite fabrication solid solution strengthening alloys, a small quantity ma...

Laser cutting of metal matrix composite, having extensive applications in aerospace and automobile industries, is important from the eminence of cut point of view. Keeping this in view, a fusion approach of Taguchi method (TM) and principal component analysis (PCA) has been functional for multi-objective optimization (MOO) of pulsed Nd: YAG laser beam cutting (LBC) of Al7075/SiCp metal matrix c...

In recent years, improving the mechanical properties of metals has become the main challenge in the modern materials and metallurgical industry. An alloying process is usually used to achieve advanced performance of metals. This paper, however, describes an alternative approach. Modification with ceramic nanoparticles, gas-dynamic treatment (GDT) and a combined treatment were investigated on a ...

Soybean-urease induced calcite precipitation (SICP) is an effective method for the improvement of sand, which forms a biocemented layer on desert sand surface to resist erosion by wind. Under this study, field tests were carried out determine how SICP approach may enhance resistance wind-induced and durability treatment in southeastern margin Tengger Desert, Ningxia Hui Autonomous Region, China...

The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...
