The definition of the physical and mechanical
properties of sugarcane trash pellets were necessary for the design
considerations relating to storage, handling and
processing equipment. The mixing ratios of ground
sugarcane trash:cassava starch:water content (1.0:0.25:0.85 and 1.0:0.25:1.40 by weight) and pelleting speeds (100, 120, 140, and 160 rpm) were considered to determine their effects...

The present
study investigated the mechanical properties and microstructure of ultrafine
grained (UFG) brass processed by four passes of equal channel angular pressing
(ECAP) and annealed at elevated temperatures. The mechanical properties of all
samples were assessed using tensile and micro-hardness tests. Microstructure
analysis was performed using optical microscopy (OM) and scanning electron
microscopy (SEM). Ultimate...

Mother-of-pearl is a monocot plants are flowering and fruiting once and then die (monokarpik). Based on its physical properties, mother-of-pearl trunk can be divided into (3) three parts, namely the center (core zone), medium (the middle between center and edge) and the edges (dermal zone). Until now, the mother-of-pearl at...

All metals have unique advantages and disadvantages in terms of their mechanical properties. Advantages such as flexibility are needed for construction and for the manufacture of sophisticated products. Some industries have improved the mechanical properties of metals by welding dissimilar ones together, such as aluminum alloy (AA) to stainless steel...
