“…Leather tanning, metallurgy, electroplating, alloying, ceramic glazes, wood preservation, water corrosion inhibition, refractory bricks, pressure-treated lumber, textile dyes, and mordant, pigments and paints production, and paper and pulp production industries contribute to the hyperaccumulation of Cr in the environment. Furthermore, anthropogenic activities, such as the dumping Cr-contaminated liquids and solids wastes, are the reason for the hyperaccumulation of Cr in the environment [8][9][10][11]. The emission of Cr from the cooling towers of the industries and the dust rising from the roads and roadsides are considered to be the most important Cr sources [12,13].…”

Chromium (Cr) is one of the top seven toxic heavy metals, being ranked 21st among the abundantly found metals in the earth’s crust. A huge amount of Cr releases from various industries and Cr mines, which is accumulating in the agricultural land, is significantly reducing the crop development, growth, and yield. Chromium mediates phytotoxicity either by direct interaction with different plant parts and metabolic pathways or it generates internal stress by inducing the accumulation of reactive oxygen species (ROS). Thus, the role of Cr-induced ROS in the phytotoxicity is very important. In the current study, we reviewed the most recent publications regarding Cr-induced ROS, Cr-induced alteration in the enzymatic antioxidant system, Cr-induced lipid peroxidation and cell membrane damage, Cr-induced DNA damage and genotoxicity, Cr-induced ultrastructural changes in cell and subcellular level, and Cr-induced alterations in photosynthesis and photosynthetic apparatus. Taken together, we conclude that Cr-induced ROS and the suppression of the enzymatic antioxidant system actually mediate Cr-induced cytotoxic, genotoxic, ultrastructural, and photosynthetic changes in plants.

“…Grafit yang dihasilkan adalah Grafit tipe A. Inokulasi merupakan metode penambahan berbagai bahan nukleasi asing (umumnya besi silikon 75%) yang efektif untuk pembentukan struktur mikro homogen tanpa matriks sementit, pencagahan pelewatan-dingin (under cooling), dan penurunan kehadiran karbida bebas. Karbida bebas ini harus dihindari karena sangat merusak kemampuan mesin dari besi cor [7][8][9]. Inokulan juga menghasilkan partikel grafit yang lebih kecil, mengurangi kecenderungan untuk membentuk rongga penyusutan dan porositas selama pemadatan besi cair, mengurangi pembentukan inklusi non-logam, dan meningkatkan sifat mekanik (dari GCI).…”

The addition of Silicon (Si) on the gray cast iron can initiate graphite dispersion where the graphite becomes smaller and more evenly distributed. This study investigated the effect of Si concentration of 2.9% and 3.8% on the fatigue strength of the gray cast iron. The Si was added by the casting process with the open ladle method. The specimens were manufactured by following the ASTM E-466. Several tests such as tensile test, Brinell hardness test, and microstructure observation were conducted prior to the fatigue testing. The results showed that the Si concentration of 3.8% tended to increase the tensile strength up to 1.3%, the hardness up to 7.6%, and fatigue limit up to 10%. Moreover, the fatigue fractured specimen of 3.8% Si showed the combination of type A and type B graphite where graphite is smaller and more evenly distributed. In addition by applying the logistic equation, the fatigue strength can be predicted well.

“…The modern industry requires new materials and technologies to limit the abrasive wear of components operating in an extreme environment [1][2][3]. Wear resistance of materials can be improved in many ways, including chemical heat treatment, coating, cladding, and cold working (e.g., shot peening) [1,[4][5][6][7].…”

This paper aimed to investigate the influence of post-weld heat treatment on the microstructure of the Mangalloy-carbon steel (C45) bimetal joint. The materials have been successfully bonded through the method of explosive welding by using ammonal explosive containing 3 % aluminum powder. The obtained bimetal joint was subjected to two different types of post-weld heat treatments: stress-relief annealing (620 • C/90 min) and normalizing (910 • C/30 min). To investigate the influence of the heat treatment on their microstructure, the joints have been subjected to light and scanning electron microscope observations, as well as the microhardness analysis. It has been reported that stress-relief annealing caused the formation of carbides in the Mangalloy layer on the grain boundaries and joint line. At the same time, normalizing resulted in the recrystallization of Mangalloy and the dissolution of cementite together with the formation of ferrite-pearlite microstructure in the C45 steel layer.
